Superior Epigastric Vein
In human anatomy, the superior epigastric veins are two or more venae comitantes which accompany either superior epigastric artery before emptying into the internal thoracic vein. They participate in the drainage of the superior surface of the diaphragm. Structure Course The superior epigastric vein originates from the internal thoracic vein. The superior epigastric veins first run between the sternal margin and the costal margin of the diaphragm, then enter the rectus sheath. They run inferiorly, coursing superficially to the fibrous layer forming the posterior leaflet of the rectus sheath, and deep to the rectus abdominis muscle. The superior epigastric veins are venae comitantes of the superior epigastric artery, and mirror its course. Distribution The superior epigastric veins participate in the drainage of the superior surface of the diaphragm. Fate The superior epigastric veins drain into the internal thoracic vein.

External Iliac Vein
The external iliac veins are large veins that connect the femoral veins to the common iliac veins. Their origin is at the inferior margin of the inguinal ligaments and they terminate when they join the internal iliac veins (to form the common iliac veins). Both external iliac veins are accompanied along their course by external iliac arteries. Structure A continuation of the femoral vein, the external iliac vein starts at the level of the inguinal ligament. It runs beside its corresponding artery and along the brim of the lesser pelvis to unite with the internal iliac vein anterior to the sacroiliac joint where it forms the common iliac vein. The left external iliac vein remains medial to the artery along its whole path. The right external iliac vein is medial to the artery, but as it ascends, it runs posterior to it. The external iliac vein is crossed by the ureter and internal iliac artery which both extend towards the middle. In males it is crossed by the vas deferens and ...

Inferior Epigastric Artery
In human anatomy, the inferior epigastric artery is an artery that arises from the external iliac artery. It is accompanied by the inferior epigastric vein; inferiorly, these two inferior epigastric vessels together travel within the lateral umbilical fold (which represents the lateral border of Hesselbach's triangle, the area through which direct inguinal hernias protrude.) The inferior epigastric artery then traverses the arcuate line of rectus sheath to enter the rectus sheath, then anastomoses with the superior epigastric artery within the rectus sheath. Structure Origin The inferior epigastric artery arises from the external iliac artery, immediately superior to the inguinal ligament. Course and relations It curves forward in the subperitoneal tissue, and then ascends obliquely along the medial margin of the abdominal inguinal ring; continuing its course upward, it pierces the transversalis fascia, and, passing in front of the linea semicircularis, ascends betw ...

Human Anatomy
Human anatomy (gr. ἀνατομία, "dissection", from ἀνά, "up", and τέμνειν, "cut") is primarily the scientific study of the morphology of the human body. Anatomy is subdivided into gross anatomy and microscopic anatomy. Gross anatomy (also called macroscopic anatomy, topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by the naked eye. Microscopic anatomy is the study of minute anatomical structures assisted with microscopes, which includes histology (the study of the organization of tissues), and cytology (the study of cells). Anatomy, human physiology (the study of function), and biochemistry (the study of the chemistry of living structures) are complementary basic medical sciences that are generally together (or in tandem) to students studying medical sciences. In some of its facets human anatomy is closely related to embryology, comparative anatomy and comparative embryology, through common ...

Vein
Veins () are blood vessels in the circulatory system of humans and most other animals that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are those of the pulmonary and fetal circulations which carry oxygenated blood to the heart. In the systemic circulation, arteries carry oxygenated blood away from the heart, and veins return deoxygenated blood to the heart, in the deep veins. There are three sizes of veins: large, medium, and small. Smaller veins are called venules, and the smallest the post-capillary venules are microscopic that make up the veins of the microcirculation. Veins are often closer to the skin than arteries. Veins have less smooth muscle and connective tissue and wider internal diameters than arteries. Because of their thinner walls and wider lumens they are able to expand and hold more blood. This greater capacity gives them the term of ''capacitance vessels''. At any time, nearly 70% o ...

Inguinal Ligament
The inguinal ligament (), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop. Structure The inguinal ligament runs from the anterior superior iliac crest of the ilium to the pubic tubercle of the pubic bone. It is formed by the external abdominal oblique aponeurosis and is continuous with the fascia lata of the thigh. There is some dispute over the attachments. Structures that pass deep to the inguinal ligament include: * Psoas major, iliacus, pectineus * Femoral nerve, artery, and vein * Lateral cutaneous nerve of thigh *Lymphatics Function The ligament serves to contain soft tissues as they course anteriorly from the trunk to the lower extremity. This structure demarcates the superior border of the femoral triangle. It demarcates the inferior border of the inguinal triangle. The midpoint ...

Terms For Anatomical Location
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek language, Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes, axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hesselbach's Triangle
In human anatomy, the inguinal triangle is a region of the abdominal wall. It is also known by the eponym Hesselbach's triangle, after Franz Kaspar Hesselbach. Structure It is defined by the following structures: * Medial border: Lateral margin of the rectus sheath. * Superolateral border: Inferior epigastric vessels. * Inferior border: Inguinal ligament. This can be remembered by the mnemonic RIP (Rectus sheath (medial), Inferior epigastric artery (lateral), Poupart's ligament (inguinal ligament, inferior). Clinical significance The inguinal triangle contains a depression referred to as the medial inguinal fossa, through which direct inguinal hernias protrude through the abdominal wall.MedNote.

Abdominal Wall
In anatomy, the abdominal wall represents the boundaries of the abdominal cavity. The abdominal wall is split into the anterolateral and posterior walls. There is a common set of layers covering and forming all the walls: the deepest being the visceral peritoneum, which covers many of the abdominal organs (most of the large and small intestines, for example), and the parietal peritoneum—which covers the visceral peritoneum below it, the extraperitoneal fat, the transversalis fascia, the internal and external oblique and transversus abdominis aponeurosis, and a layer of fascia, which has different names according to what it covers (e.g., transversalis, psoas fascia). In medical vernacular, the term 'abdominal wall' most commonly refers to the layers composing the anterior abdominal wall which, in addition to the layers mentioned above, includes the three layers of muscle: the transversus abdominis (transverse abdominal muscle), the internal oblique, internal (obliquus internus) a ...

Rectus Sheath
The rectus sheath (also called the rectus fascia.) is a tough fibrous compartment formed by the aponeuroses of the transverse abdominal, transverse abdominal muscle, and the internal oblique, internal and external oblique muscles. It contains the Rectus abdominis muscle, rectus abdominis and Pyramidalis muscle, pyramidalis muscles, as well as vessels and nerves. Structure The rectus sheath extends between the inferior costal margin and costal cartilages of ribs 5-7 superiorly, and the pubic crest inferiorly. Studies indicate that all three aponeuroses constituting the rectus sheath are in fact bilaminar. Below the costal margin Superficial/anterior to the anterior layer of the rectus sheath are the following two layers: # Camper's fascia (anterior part of superficial fascia) # Scarpa's fascia (posterior part of the superficial fascia) Deep/posterior posterior layer of the rectus sheath (where present) are the following three layers: # transversalis fascia # extraperitoneal ...
