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.

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]
Goss was the esteemed editor of the 25th edition of the seminal classic Gray’s Anatomy. Internationally lauded as the authority on all things anatomical, Gray’s Anatomy had been considered essential for any would-be physician to own since it was first published in London in 1858. It was written by Dr. Henry Gray and illustrated by Henry ...
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.
