The internal iliac artery arises at the bifurcation of the common iliac artery, opposite the lumbosacral articulation, and, passing downward to the upper margin of the greater sciatic foramen, divides into two large trunks, an anterior and a posterior. It is posterior to the ureter, [2] anterior to the internal iliac vein, [2] anterior to the ...
The lumbar arteries are arteries located in the lower back or lumbar region. The lumbar arteries are in parallel with the intercostals. They are usually four in number on either side, and arise from the back of the aorta, opposite the bodies of the upper four lumbar vertebrae. A fifth pair, small in size, is occasionally present: they arise ...
The iliolumbar vein is the vena comitans of the iliolumbar artery. The obturator nerve crosses superficial to it. [1] A single vein is found more commonly than a double vein. [2] It drains vertebral segments four and five. [3] It is closely related to the ascending lumbar vein. [3]
Structure. The abdominal aorta begins at the level of the diaphragm, crossing it via the aortic hiatus, technically behind the diaphragm, at the vertebral level of T12. [ 1 ] It travels down the posterior wall of the abdomen, anterior to the vertebral column. It thus follows the curvature of the lumbar vertebrae, that is, convex anteriorly.
Anatomical terminology. [edit on Wikidata] In human anatomy, the common iliac veins are formed by the external iliac veins and internal iliac veins. The left and right common iliac veins come together in the abdomen at the level of the fifth lumbar vertebra, [1] forming the inferior vena cava. They drain blood from the pelvis and lower limbs.
The external iliac artery provides the main blood supply to the legs. It passes down along the brim of the pelvis and gives off two large branches - the "inferior epigastric artery" and a "deep circumflex artery." These vessels supply blood to the muscles and skin in the lower abdominal wall. The external iliac artery passes beneath the ...
Obturator artery. The relations of the femoral and abdominal inguinal rings, seen from within the abdomen. Right side. (Obturator artery is visible at bottom.) Internal iliac artery and some branches. The obturator artery is a branch of the internal iliac artery that passes antero-inferiorly (forwards and downwards) on the lateral wall of the ...
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])
