In human anatomy, the superior epigastric artery is a terminal [1] branch of the internal thoracic artery that provides arterial supply to the abdominal wall, and upper rectus abdominis muscle. It enters the rectus sheath to descend upon the inner surface of the rectus abdominis muscle. It ends by anastomosing with the inferior epigastric artery.
In anatomy, the abdominal wall represents the boundaries of the abdominal cavity.The abdominal wall is split into the anterolateral and posterior walls. [1]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 ...
Divides in hilum of kidney. Both arteries give inferior suprarenal arteries and ureteral branches. gonadal: L2: Visceral: yes: ant. Ovarian artery in females; testicular artery in males lumbar: L1-L4: Parietal: yes: post. Four on each side that supply the abdominal wall and spinal cord. The fifth pair is the lumbar branches of the iliolumbar ...
Large arteries (such as the aorta) are composed of many different types of cells, namely endothelial, smooth muscle, fibroblast, and immune cells. [2] As with veins, the arterial wall consists of three layers called tunics, namely the tunica intima, tunica media, and tunica externa, from innermost to outermost.
In human anatomy, the inferior epigastric artery is an artery that arises from the external iliac artery. [1]: 225 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. [2])
The arcuate line of rectus sheath (the arcuate line or the semicircular line of Douglas) is a line of demarcation [1] corresponding to the free inferior margin of the posterior layer of the rectus sheath [2] inferior to which only the anterior layer of the rectus sheath is present [3] and the rectus abdominis muscle is therefore in direct contact with the transversalis fascia. [1]

Venous vasa vasorae, that originate within the vessel wall of the artery but then drain into the main lumen or branches of concomitant vein. [1] Depending on the type of vasa vasorum, it penetrates the vessel wall starting at the intimal layer (vasa vasorum interna) or the adventitial layer (vasa vasorum externa). Due to higher radial and ...
