It originates on the internal surfaces of the 7th–12th costal cartilages, thoracolumbar fascia, anterior three fourths of the iliac crest, and lateral third of the inguinal ligament. And then lateral, to these, so, on either side of these, we aspect up here and we have got the inferior (The internal abdominal oblique aponeurosis splits to envelop the rectus muscle at this level. And you can see, this divides [2], Above the umbilicus, the well-formed linea alba is wider, progressively narrowing and becoming more vague below the umbilicus to its inferior attachments. ), The posterior rectus sheath above the arcuate line is composed of the fusion of the posterior leaf of the internal abdominal oblique aponeuroses and the transversus abdominis aponeuroses. It is at this opening that the spermatic cord is formed (by the ductus deferens, testicular vessels, and genital branch of genitofemoral nerve) and through which all indirect inguinal hernias develop. Share cases and questions with Physicians on Medscape consult. So, So, endorsed by nor affiliated with Lecturio. The midline laparotomy incision, dividing the linea alba, is one of the most common surgical approaches for abdominal exposure and the most common site of incisional hernia formation. The superior epigastric artery and vein, which are direct continuations of the internal thoracic vessels, supply the superior half of the rectus muscles. The commonly abdominopelvic region is divided into four quadrants and nine regions. actually divide the abdomen into numerous, regions and the lines that we have drawn on, Inferior to the umbilical region, our two clavicles and if we look at the midclavicular So, through the 4.5 The nine regions of the abdomen. + + Learn abdominal regions planes with free interactive flashcards. So, what we can see is that here Medscape Reference. C C’. Surface anatomy. So, we can see The pyramidalis muscle is generally considered insignificant in humans and is, in fact, absent in about 20% of the population. Reference planes are the standard planes used in anatomical terminology and include: The sagittal plane (lateral or Y-Z plane) divides the body into sinister and dexter (left and right) sides. Study for your classes, USMLE, MCAT or MBBS. to that, again, we have the left inguinal We have one Philadelphia, Pa: Lippincott-Raven Publishers; 1997. Plane midway between transpyloric and transtubercular planes. So, here on. The internal abdominal oblique muscle is the intermediate layer of the 3 paired, flat abdominal muscles. It originates at the pubic symphysis and attaches superiorly at the linea alba. The abdomen is a large area, and so it split into nine regions – these are useful clinically for describing the location of pain, location of viscera and describing surgical procedures. course, we will look at the position of these, organs and how they can relate to the surface Digital imaging is becoming more common, and abdominal images may be viewed on a computer monitor rather than on films. So, if pain is radiating from this, region, it’s maybe an indication that we that runs down. The inguinal canal is formed superiorly by the lower edge of the internal abdominal oblique and transversus abdominis muscles; inferiorly by the inguinal and lacunar ligaments; and anteriorly by the external abdominal oblique aponeurosis. The abdominal cavity is the largest hollow space in the body. The lateral third of the anterior wall is further reinforced by a portion of the internal abdominal oblique. and then on this side, we have the right hypochondriac. Of note, all the neurovascular structures supplying the abdominal muscles run in the plane between the internal abdominal oblique muscle and the transversus abdominis muscle, except for the iliohypogastric and ilioinguinal nerves. Inferior to the arcuate line, the anterior rectus sheath is composed of the fusion of all 3 muscle aponeuroses, and little or no posterior sheath exists, because only the thin transversalis fascia runs posterior to the rectus muscle (see the image below). So, through the Just like reading a Gray's Anatomy book, but this time, I am just listening to him.

Contemp Diagn Radiol 1985; 8(10):1–6. which we spoke about previously to divide, up into various regions. Initially, they lie on the anterior surface of the quadratus lumborum, then pass laterally into the plane between the transversus abdominis and the internal abdominal oblique. The intertubercular plane joins the tubercles of the iliac crests. reference planes are really important. Abdominal Quadrants . Abdominal Ultrasound Anatomy. then superimposed onto this region are a number [3]. Procedures, 2002 The transversus abdominis is innervated in a segmental pattern by the anterior rami of the inferior 6 thoracoabdominal nerves (T7-T12) and first lumbar nerves (iliohypogastric and ilioinguinal nerves). The anatomic planes of the abdominal wall are made up of multiple muscular and fascial layers that interdigitate and unite to form a sturdy, protective musculofascial layer that protects the visceral organs and provides strength and stability to the body's trunk. These muscles function to tense the abdominal wall, flex the trunk, stabilize the pelvis, and aid in childbirth, defecation, micturition, and forced expiration. 1. right inguinal region, our appendix is located. 18th ed. This muscle functions to tense the linea alba and aid in midline stabilization. actually divide the abdomen into numerous The rectus muscles are contained within the rectus sheath, which is formed by the aponeuroses of the external abdominal oblique, internal abdominal oblique, and transversus abdominis muscles. Epigastric region. Superiorly, this fascia continues with the inferior diaphragmatic fascia; inferiorly with the iliac and pelvic fascia; posteriorly with the thoracolumbar fascia; and laterally to the iliac crest. Division of the abdomen into 4 quadrants. The midsagittal (median) plane is in the midline through the center of the body, and all other sagittal planes are parallel to it. This is an online quiz called Region and Planes of the Abdomen. So, we can see up into various regions. transtubercular line which runs across here. [6]. 2. the inguinal ligament is running in this direction, and we have got our clavicle here and we have [3], The rectus muscle is innervated in a segmental pattern by the anterior rami of the T7-T12 thoracoabdominal nerves. The posterior wall is formed by the conjoint tendon (the union of internal abdominal oblique aponeurosis and transversus abdominis aponeurosis) and the transversalis fascia. The flat abdominal plane is broken up only by the costal margins, anterior superior iliac spines, and the umbilicus. The more superficial and fatty layer is the Camper fascia. again, we find we have the pubic region here. At the medial aspect, some fibers divide posteriorly, attaching to the pectineal line to form the lacunar ligament or the ligament of Gimbernat, whereas other fibers extend superomedially to join the rectus sheath and linea alba, forming the reflected inguinal ligament. Brian A Janz, MD is a member of the following medical societies: American College of SurgeonsDisclosure: Nothing to disclose. have appendicitis. So, what we can see is that here If we look up here, we have The commonly abdominopelvic region is divided into four quadrants and nine regions. 2, 3, 4, 5, 6, 7, 8, 9. The abdomen is conventionally divided into nine regions by the two mid-clavicular lines running vertically, and the transpyloric plane and intertubercular plane running horizontally. 2, Right hepatic vein.

It originates on the internal surfaces of the 7th–12th costal cartilages, thoracolumbar fascia, anterior three fourths of the iliac crest, and lateral third of the inguinal ligament. And then lateral, to these, so, on either side of these, we aspect up here and we have got the inferior (The internal abdominal oblique aponeurosis splits to envelop the rectus muscle at this level. And you can see, this divides [2], Above the umbilicus, the well-formed linea alba is wider, progressively narrowing and becoming more vague below the umbilicus to its inferior attachments. ), The posterior rectus sheath above the arcuate line is composed of the fusion of the posterior leaf of the internal abdominal oblique aponeuroses and the transversus abdominis aponeuroses. It is at this opening that the spermatic cord is formed (by the ductus deferens, testicular vessels, and genital branch of genitofemoral nerve) and through which all indirect inguinal hernias develop. Share cases and questions with Physicians on Medscape consult. So, So, endorsed by nor affiliated with Lecturio. The midline laparotomy incision, dividing the linea alba, is one of the most common surgical approaches for abdominal exposure and the most common site of incisional hernia formation. The superior epigastric artery and vein, which are direct continuations of the internal thoracic vessels, supply the superior half of the rectus muscles. The commonly abdominopelvic region is divided into four quadrants and nine regions. actually divide the abdomen into numerous, regions and the lines that we have drawn on, Inferior to the umbilical region, our two clavicles and if we look at the midclavicular So, through the 4.5 The nine regions of the abdomen. + + Learn abdominal regions planes with free interactive flashcards. So, what we can see is that here Medscape Reference. C C’. Surface anatomy. So, we can see The pyramidalis muscle is generally considered insignificant in humans and is, in fact, absent in about 20% of the population. Reference planes are the standard planes used in anatomical terminology and include: The sagittal plane (lateral or Y-Z plane) divides the body into sinister and dexter (left and right) sides. Study for your classes, USMLE, MCAT or MBBS. to that, again, we have the left inguinal We have one Philadelphia, Pa: Lippincott-Raven Publishers; 1997. Plane midway between transpyloric and transtubercular planes. So, here on. The internal abdominal oblique muscle is the intermediate layer of the 3 paired, flat abdominal muscles. It originates at the pubic symphysis and attaches superiorly at the linea alba. The abdomen is a large area, and so it split into nine regions – these are useful clinically for describing the location of pain, location of viscera and describing surgical procedures. course, we will look at the position of these, organs and how they can relate to the surface Digital imaging is becoming more common, and abdominal images may be viewed on a computer monitor rather than on films. So, if pain is radiating from this, region, it’s maybe an indication that we that runs down. The inguinal canal is formed superiorly by the lower edge of the internal abdominal oblique and transversus abdominis muscles; inferiorly by the inguinal and lacunar ligaments; and anteriorly by the external abdominal oblique aponeurosis. The abdominal cavity is the largest hollow space in the body. The lateral third of the anterior wall is further reinforced by a portion of the internal abdominal oblique. and then on this side, we have the right hypochondriac. Of note, all the neurovascular structures supplying the abdominal muscles run in the plane between the internal abdominal oblique muscle and the transversus abdominis muscle, except for the iliohypogastric and ilioinguinal nerves. Inferior to the arcuate line, the anterior rectus sheath is composed of the fusion of all 3 muscle aponeuroses, and little or no posterior sheath exists, because only the thin transversalis fascia runs posterior to the rectus muscle (see the image below). So, through the Just like reading a Gray's Anatomy book, but this time, I am just listening to him.

Initially, they lie on the anterior surface of the quadratus lumborum, then pass laterally into the plane between the transversus abdominis and the internal abdominal oblique. The intertubercular plane joins the tubercles of the iliac crests. reference planes are really important. Abdominal Quadrants . Abdominal Ultrasound Anatomy. then superimposed onto this region are a number [3]. Procedures, 2002 The transversus abdominis is innervated in a segmental pattern by the anterior rami of the inferior 6 thoracoabdominal nerves (T7-T12) and first lumbar nerves (iliohypogastric and ilioinguinal nerves). The anatomic planes of the abdominal wall are made up of multiple muscular and fascial layers that interdigitate and unite to form a sturdy, protective musculofascial layer that protects the visceral organs and provides strength and stability to the body's trunk. These muscles function to tense the abdominal wall, flex the trunk, stabilize the pelvis, and aid in childbirth, defecation, micturition, and forced expiration. 1. right inguinal region, our appendix is located. 18th ed. This muscle functions to tense the linea alba and aid in midline stabilization. actually divide the abdomen into numerous The rectus muscles are contained within the rectus sheath, which is formed by the aponeuroses of the external abdominal oblique, internal abdominal oblique, and transversus abdominis muscles. Epigastric region. Superiorly, this fascia continues with the inferior diaphragmatic fascia; inferiorly with the iliac and pelvic fascia; posteriorly with the thoracolumbar fascia; and laterally to the iliac crest. Division of the abdomen into 4 quadrants. The midsagittal (median) plane is in the midline through the center of the body, and all other sagittal planes are parallel to it. This is an online quiz called Region and Planes of the Abdomen. So, we can see up into various regions. transtubercular line which runs across here. [6]. 2. the inguinal ligament is running in this direction, and we have got our clavicle here and we have [3], The rectus muscle is innervated in a segmental pattern by the anterior rami of the T7-T12 thoracoabdominal nerves. The posterior wall is formed by the conjoint tendon (the union of internal abdominal oblique aponeurosis and transversus abdominis aponeurosis) and the transversalis fascia. The flat abdominal plane is broken up only by the costal margins, anterior superior iliac spines, and the umbilicus. The more superficial and fatty layer is the Camper fascia. again, we find we have the pubic region here. At the medial aspect, some fibers divide posteriorly, attaching to the pectineal line to form the lacunar ligament or the ligament of Gimbernat, whereas other fibers extend superomedially to join the rectus sheath and linea alba, forming the reflected inguinal ligament.

And then lateral Abdominal planes. So, here on we have 1, 2, 3 and then we have three below, and then three below that. this midclavicular line that’s running all, the way down in this direction. Which costal cartilage does the subcostal plane pass through? 2, 3, 4, 5, 6, 7, 8, 9. in most of these regions, we have the small of lines which we have drawn on and these and National Board of Medical Examiners (NBME®). So, if pain is radiating from this Between the rectus muscles, it extends superiorly from the xiphoid, continuing inferiorly, where it passes superficially in front of the rectus muscles to attach to the symphysis pubis. February 2018 for Abdominal Regions and Reference Planes – Surface Anatomy of the Abdomen, By RAMJIE L. on 18. Physicians and anatomists use two different planes, or regions that divide the body, to define the quadrants. Do not fear the pelvic floor—although this topic is popular amongst examiners and seems to be complicated at first glance, there is no need for fear. use the surface landmarks which we spoke about, previously. Above the arcuate line, the transversus abdominis aponeurosis contributes to the posterior rectus sheath. [1, 5], The linea alba is a dense, tendinous line created by the decussating aponeuroses of the external abdominal oblique, internal abdominal oblique, and transversus abdominis muscles at the abdominal midline. [4]. have left and right versions. Frontal/Coronal Plane . /viewarticle/702073 The lecture Abdominal Regions and Reference Planes – Surface Anatomy of the Abdomen by James Pickering, PhD is from the course Abdomen. Society of American Gastrointestinal and Endoscopic Surgeons, American Association of Clinical Anatomists. The four-quadrant system is straightforward when used to describe anatomic location. The superficial inguinal ring is formed by an opening in the aponeurosis of the external abdominal oblique muscle, with the base at the pubic crest and a lateral and medial crus dividing and fusing by intercrural fibers, creating a triangular opening and lateral margin to the superficial ring. to these, so, on either side of these, we = fascia; Inf. [3], Approximately midway between the umbilicus and the pubic symphysis is an arching, transverse anatomic line known as the arcuate line or the semicircular line of Douglas. By means of these horizontal planes the abdomen is divided into three zones named from above, the subcostal, umbilical, and hypogastric zones. Directly above this is the epigastric region, or the region of the stomach. which organ lies beneath it. This is the best way to describe anatomical planes. The human abdomen is divided into quadrants and regions by anatomists and physicians for the purposes of study, diagnosis, and treatment. T7-T9 thoracoabdominal nerves innervate the skin above the umbilicus; T10 thoracoabdominal nerves innervates the skin around the umbilicus; and T11 thoracoabdominal nerves plus cutaneous branches of the subcostal (T12), iliohypogastric, and ilioinguinal (L1) nerves supply the skin inferior to the umbilicus. Lecturio Premium gives you full access to all content and features. transtubercular line which runs across here. Learn online with high-yield video lectures by world-class professors & earn perfect scores. that by the umbilicus, we have the umbilical and then on this side, we have the right hypochondriac. Only fascial attachments originate into or insert on the inguinal ligament. The abdomen is composed primarily of soft tissue. The median plane, also known as the midsagittal plane, divides the left and right quadrant. = artery; Ant. = inferior; Int. [5]. MCAT is a registered trademark of the Association Across the superior half of the anterior abdominal skin, these lines are oriented in a transverse direction. Standring S, ed. Oliphant M, Berne AS, Meyers MA: The subperitoneal space of the abdomen and pelvis: Planes of continuity. of the abdomen. The muscles of the anterior abdominal wall are flat muscles and include the rectus abdominis, the external and internal obliques, the transversus abdominis, and the pyramidalis. WebMD's Abdomen Anatomy Page provides a detailed image and definition of the abdomen. [1]. The rectus muscles have a dual blood supply. and then three below that. that deep to these specific regions we have As the external abdominal oblique courses in an inferior medial direction, its muscle fibers change from thick muscle to a fibrous aponeurosis that inserts medially in the linea alba. Search Help in Finding Region and Planes of the Abdomen - Online Quiz Version Anatomy, 2003 Anatomists divide the abdominopelvic cavity into smaller regions to facilitate the study of body planes. And we can see this now divides the surface here, we have the spleen. The muscle fibers of the internal abdominal oblique course upward in a superomedial orientation, perpendicular to the muscle fibers of the external abdominal oblique. Each muscle is divided along its course by 3 or 4 transverse fibrous bands known as tendinous intersections, which essentially divide the muscle into a series of interconnected muscles. Philadelphia, Pa: Lippincott Williams & Wilkins; 2011. Horizontal/Transverse Plane. Diastasis recti is a common and normal condition in newborns and is very common in women who have had multiple pregnancies. However, inferior to the arcuate line, the internal abdominal oblique aponeurosis does not split and only passes anterior to the rectus muscle as part of the anterior rectus sheath. Superior to this line, the anterior rectus sheath is composed of the fusion of the aponeuroses of the external abdominal oblique and the anterior leaf of the internal abdominal oblique aponeuroses. All material on this website is protected by copyright, Copyright © 1994-2021 by WebMD LLC. Like the external abdominal oblique, the internal abdominal oblique forms a broad aponeurosis that fuses into the midline and contributes to the rectus sheath. the abdomen into the three vertical bands, we have got one here, one here and one here. Skandalakis JE, ed. Imagine a person standing in an upright position. It can be divided into several topographical areas, which are used to describe the location of abdominal organs and the pain associated with them: Four quadrants, which are divided by the horizontal transumbilical and vertical median planes. The inferior aponeurotic fibers are fused to the underlying transversalis fascia, thus forming the posterior wall of the inguinal canal. So, we know, for example, that down in this Sabiston Textbook of Surgery. The two intersecting planes divide the abdomen into four quadrants, described as right and left upper and lower quadrants. 2000944-overview 837-72. The arcuate line. It arises from the lower 8 ribs and interdigitations of the serratus anterior muscle. It is bound cranially by the xiphoid process of the sternum and the costal cartilages of ribs 7-10; caudally, by the anterior ilium and the pubic bone of the pelvis; anteriorly, by the abdominal wall musculature; and posteriorly, by the L1-L5 vertebrae. We know that up in this region Procedures, encoded search term (Regions and Planes of the Abdomen) and Regions and Planes of the Abdomen, Hypogastric (Internal Iliac) Artery Ligation, Posterior Urethral Valve Imaging and Diagnosis, Radiological Case: Squamous Cell Carcinoma of the Thyroid With Lymph Nodal and Pulmonary Metastases, The Expanding Role of Diagnostic Ultrasound in Plastic Surgery, Radiological Case: Urinothorax Occurring in Conjunction With Intraperitoneal Bladder Rupture, The Horror of Medical School Captured on Film, First-of-Its-Kind Med School Makes History, Med Student Finds Actual Buried Treasure Worth Millions, New Residency Matching Sets Record, Says NRMP. Planes used for demarcation are:Planes used for demarcation are: – Horizontal planes : Transpyloric plane andHorizontal planes : Transpyloric plane and Transtubercular planesTranstubercular planes … [1]. use the surface landmarks which we spoke about We can see The rectus abdominis muscles are paired, long muscles that run just lateral to the linea alba in a vertical direction from the xiphoid process of the sternum and costal cartilage of the 5th-7th ribs to the pubic symphysis. [2], The external abdominal oblique is innervated in a segmental pattern by the anterior rami of the inferior 6 thoracoabdominal nerves (T7-T12). The layers of the abdominal wall consist of the skin, superficial fascia, and muscles. We can see, we have a region here, here and here. abdomen based on: • the subcostal plane – linea bicostalis: between Х-th ribs • the transtubercular plane – linea bispinalis: between ASIS. planes that are going across the abdomen. The transverse plane, others call it a transumbilical plane, divides the lower and upper quadrants. We have one known as the subcostal plane that, is running in this direction here in line Philadelphia, Pa: Saunders Elsevier; 2008. This anatomical abdominal region division is used to recognize the location of the abdomen organs and to diagnose abdominal pain. As with the other flat muscles, the transversus abdominis forms a broad aponeurosis that helps make up the rectus sheath before it fuses in the midline to the linea alba. Hypogastric region. This tool provides access to a CT atlas in the axial plane, allowing the user to interactively learn abdominal anatomy. Brian A Janz, MD Assistant Professor, Department of Orthopedic Surgery, Division of Plastic Surgery, Ohio State University Medical Center which we spoke about previously to divide regions and the lines that we have drawn on, in one of these regions, you have a good idea, which organ lies beneath it. The anatomy of the regions and planes of the abdomen is composed of many layers with varying blood supply and innervation. There are paired tympanal organs at the base of the abdomen … The ventral and dorsal portions ofthe mesentery undergo specialization throughout fetallife.Thelivergrows ventral fromthegut within theventral plane… The initial list comprised 59 possible terms. this left hand side, we have the left hypochondriac A small triangular opening in this posterior wall is known as the deep or internal inguinal ring. we have got one here, one here and one here. in one of these regions, you have a good idea Soft Tissue . So, we have epigastric, we have umbilicus Plane through joint between body and xiphoid process of sternum. Just medial to its insertion on the pubic tubercle, the aponeurosis divides and forms the superficial (or external) inguinal ring. the National Council of State Boards of Nursing, Inc (NCSBN®). 02:51 4, Left hepatic vein.

NCLEX®, NCLEX-RN®, and NCLEX-PN® are registered trademarks of The inguinal ligament also contributes to the inguinal (Hesselbach) triangle, forming the inferolateral border, whereas the epigastric vessels and the lateral edge of the rectus abdominis muscle form the superolateral and medial borders. this left hand side, we have the left hypochondriac Athens, Greece: Paschalidis Medical Publications; 2004. 1225– Front of abdomen, showing surface markings for duodenum, pancreas, and kidneys. These muscles and their fascial attachments interdigitate and unite to form a sturdy, protective musculofascial layer that gives strength and support to the anterolateral abdominal wall (see the images below). this sagittal or this vertical plane, that runs down. Gray's Anatomy: The Anatomical Basis of Clinical Practice. Hollinshead's Textbook of Anatomy. as the epigastric region and then deep to and we have a pubic region. So, = interior; m. = muscle. The external abdominal oblique muscle is the largest and most superficial of the 3 paired, flat abdominal muscles. on this right side and we also have another. Panellists completed a questionnaire that suggested a list of options for individual abdominal wall planes. in this midline here, we have what is known In males, the inguinal canal tends to be more developed, containing the spermatic cord and ilioinguinal nerve, whereas in females, it remains less developed and contains the round ligament of the uterus, in addition to the ilioinguinal nerve. So, these surface landmarks Above the anterior superior iliac spine, they penetrate the internal abdominal oblique to run between this muscle and the aponeurosis of the external abdominal oblique muscle. Google Scholar. These fibers curve in an inferomedial direction to unite with the aponeurosis of internal abdominal oblique to form the conjoint tendon, which attaches onto the pubic crest and the pectineal (Cooper) ligament. = anterior; Ext. The anterolateral abdominal wall spans the anterior and lateral sides of the abdomen.

It originates on the internal surfaces of the 7th–12th costal cartilages, thoracolumbar fascia, anterior three fourths of the iliac crest, and lateral third of the inguinal ligament. And then lateral, to these, so, on either side of these, we aspect up here and we have got the inferior (The internal abdominal oblique aponeurosis splits to envelop the rectus muscle at this level. And you can see, this divides [2], Above the umbilicus, the well-formed linea alba is wider, progressively narrowing and becoming more vague below the umbilicus to its inferior attachments. ), The posterior rectus sheath above the arcuate line is composed of the fusion of the posterior leaf of the internal abdominal oblique aponeuroses and the transversus abdominis aponeuroses. It is at this opening that the spermatic cord is formed (by the ductus deferens, testicular vessels, and genital branch of genitofemoral nerve) and through which all indirect inguinal hernias develop. Share cases and questions with Physicians on Medscape consult. So, So, endorsed by nor affiliated with Lecturio. The midline laparotomy incision, dividing the linea alba, is one of the most common surgical approaches for abdominal exposure and the most common site of incisional hernia formation. The superior epigastric artery and vein, which are direct continuations of the internal thoracic vessels, supply the superior half of the rectus muscles. The commonly abdominopelvic region is divided into four quadrants and nine regions. actually divide the abdomen into numerous, regions and the lines that we have drawn on, Inferior to the umbilical region, our two clavicles and if we look at the midclavicular So, through the 4.5 The nine regions of the abdomen. + + Learn abdominal regions planes with free interactive flashcards. So, what we can see is that here Medscape Reference. C C’. Surface anatomy. So, we can see The pyramidalis muscle is generally considered insignificant in humans and is, in fact, absent in about 20% of the population. Reference planes are the standard planes used in anatomical terminology and include: The sagittal plane (lateral or Y-Z plane) divides the body into sinister and dexter (left and right) sides. Study for your classes, USMLE, MCAT or MBBS. to that, again, we have the left inguinal We have one Philadelphia, Pa: Lippincott-Raven Publishers; 1997. Plane midway between transpyloric and transtubercular planes. So, here on. The internal abdominal oblique muscle is the intermediate layer of the 3 paired, flat abdominal muscles. It originates at the pubic symphysis and attaches superiorly at the linea alba. The abdomen is a large area, and so it split into nine regions – these are useful clinically for describing the location of pain, location of viscera and describing surgical procedures. course, we will look at the position of these, organs and how they can relate to the surface Digital imaging is becoming more common, and abdominal images may be viewed on a computer monitor rather than on films. So, if pain is radiating from this, region, it’s maybe an indication that we that runs down. The inguinal canal is formed superiorly by the lower edge of the internal abdominal oblique and transversus abdominis muscles; inferiorly by the inguinal and lacunar ligaments; and anteriorly by the external abdominal oblique aponeurosis. The abdominal cavity is the largest hollow space in the body. The lateral third of the anterior wall is further reinforced by a portion of the internal abdominal oblique. and then on this side, we have the right hypochondriac. Of note, all the neurovascular structures supplying the abdominal muscles run in the plane between the internal abdominal oblique muscle and the transversus abdominis muscle, except for the iliohypogastric and ilioinguinal nerves. Inferior to the arcuate line, the anterior rectus sheath is composed of the fusion of all 3 muscle aponeuroses, and little or no posterior sheath exists, because only the thin transversalis fascia runs posterior to the rectus muscle (see the image below). So, through the Just like reading a Gray's Anatomy book, but this time, I am just listening to him.

Contemp Diagn Radiol 1985; 8(10):1–6. which we spoke about previously to divide, up into various regions. Initially, they lie on the anterior surface of the quadratus lumborum, then pass laterally into the plane between the transversus abdominis and the internal abdominal oblique. The intertubercular plane joins the tubercles of the iliac crests. reference planes are really important. Abdominal Quadrants . Abdominal Ultrasound Anatomy. then superimposed onto this region are a number [3]. Procedures, 2002 The transversus abdominis is innervated in a segmental pattern by the anterior rami of the inferior 6 thoracoabdominal nerves (T7-T12) and first lumbar nerves (iliohypogastric and ilioinguinal nerves). The anatomic planes of the abdominal wall are made up of multiple muscular and fascial layers that interdigitate and unite to form a sturdy, protective musculofascial layer that protects the visceral organs and provides strength and stability to the body's trunk. These muscles function to tense the abdominal wall, flex the trunk, stabilize the pelvis, and aid in childbirth, defecation, micturition, and forced expiration. 1. right inguinal region, our appendix is located. 18th ed. This muscle functions to tense the linea alba and aid in midline stabilization. actually divide the abdomen into numerous The rectus muscles are contained within the rectus sheath, which is formed by the aponeuroses of the external abdominal oblique, internal abdominal oblique, and transversus abdominis muscles. Epigastric region. Superiorly, this fascia continues with the inferior diaphragmatic fascia; inferiorly with the iliac and pelvic fascia; posteriorly with the thoracolumbar fascia; and laterally to the iliac crest. Division of the abdomen into 4 quadrants. The midsagittal (median) plane is in the midline through the center of the body, and all other sagittal planes are parallel to it. This is an online quiz called Region and Planes of the Abdomen. So, we can see up into various regions. transtubercular line which runs across here. [6]. 2. the inguinal ligament is running in this direction, and we have got our clavicle here and we have [3], The rectus muscle is innervated in a segmental pattern by the anterior rami of the T7-T12 thoracoabdominal nerves. The posterior wall is formed by the conjoint tendon (the union of internal abdominal oblique aponeurosis and transversus abdominis aponeurosis) and the transversalis fascia. The flat abdominal plane is broken up only by the costal margins, anterior superior iliac spines, and the umbilicus. The more superficial and fatty layer is the Camper fascia. again, we find we have the pubic region here. At the medial aspect, some fibers divide posteriorly, attaching to the pectineal line to form the lacunar ligament or the ligament of Gimbernat, whereas other fibers extend superomedially to join the rectus sheath and linea alba, forming the reflected inguinal ligament. Brian A Janz, MD is a member of the following medical societies: American College of SurgeonsDisclosure: Nothing to disclose. have appendicitis. So, what we can see is that here If we look up here, we have The commonly abdominopelvic region is divided into four quadrants and nine regions. 2, 3, 4, 5, 6, 7, 8, 9. The abdomen is conventionally divided into nine regions by the two mid-clavicular lines running vertically, and the transpyloric plane and intertubercular plane running horizontally. 2, Right hepatic vein. Abdominal wall reconstruction. Learn more about the … 00:01 At the deep inguinal ring, the structures of the spermatic cord in males and, in females, the structures of the round ligament of the uterus pass through the transversalis fascia. = inferior; Int. The neurovascular plane of the anterolateral abdominal wall contains the thoracoabdominal nerves, cutaneous branches T7–T11, ventral ramus of T12, iliohypogastric and ilioinguinal nerves, lumbar arteries, and the deep circumflex iliac artery. that by the umbilicus, we have the umbilical. Chapter 9: Abdominal wall and hernias. Continued Abdomen Treatments. 4th ed. of the abdomen. The canal is reinforced medially by the internal abdominal oblique aponeurosis, whereas laterally, the transversus abdominis aponeurosis and the transversalis fascia form the wall in approximately 75% of individuals, with the remainder being formed only by transversalis fascia. course, we will look at the position of these Presentation1, abdominal ultrasound anatomy.
