The obturator artery is a branch of the internal iliac artery that passes antero-inferiorly (forwards and downwards) on the lateral wall of the pelvis, to the upper part of the obturator foramen, and, escaping from the pelvic cavity through the obturator canal, it divides into an anterior branch and a posterior branch.
The obturator nerve is the primary nerve supplying this compartment. The obturator artery is the blood supply to the medial thigh. The muscles in the compartment are: gracilis; adductor longus; adductor brevis; adductor magnus; The obturator externus muscle is sometimes considered part of this group, [1] [2] [3] and sometimes excluded. [4]
The ascending branch of medial circumflex femoral artery is a small artery in the thigh. It branches of the medial circumflex femoral artery and is distributed to the adductor muscles of the hip. It anastomoses with the obturator artery. It also serves as an important blood supply to the head of the femur.
Variations in origin and course of obturator artery. (Obturator canal not labeled, but visible at bottom center of each diagram.) The obturator canal is formed between the obturator membrane and the pelvis. [1] The obturator artery, obturator vein, and obturator nerve all travel through the canal.
The acetabular branch of the obturator artery supplies the acetabulum through the acetabular notch. The pubic branches supply the pelvic surface of the acetabulum. Deep branches of the superior gluteal artery supply the superior region and the inferior gluteal artery supplies the postero-inferior region. [7]
The acetabular branch is an artery in the hip that arises from the medial circumflex femoral artery opposite the acetabular notch and enters the hip-joint beneath the transverse ligament in company with an articular branch from the obturator artery. It supplies the fat in the bottom of the acetabulum, and is continued along the ligament to the ...
The obturator membrane is a thin fibrous sheet, which almost completely closes the obturator foramen.. Its fibers are arranged in interlacing bundles mainly transverse in direction; the uppermost bundle is attached to the obturator tubercles and completes the obturator canal for the passage of the obturator vessels and nerve.
The higher supply of oxygen allows the teleost retina to be thick and have few blood vessels thereby increasing its sensitivity to light. [10] In addition to raising the P O 2 {\displaystyle {P_{\rm {O_{2}}}}} , the choroid rete has evolved to raise the temperature of the eye in some teleosts and sharks .
