The posterior branch of the obturator artery follows the posterior margin of the foramen and turns forward on the inferior ramus of the ischium, where it anastomoses with the anterior branch.

It gives twigs to the muscles attached to the ischial tuberosity and anastomoses with the inferior gluteal.

It also supplies an articular branch which enters the hip-joint through the acetabular notch, ramifies in the fat at the bottom of the acetabulum and sends a twig along the ligamentum teres to the head of the femur.

The obturator artery 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 both an anterior and a posterior branch.

acetabulum is a surface of the pelvis. The head of the femur meets with the pelvis at the acetabulum, forming the hip joint.

Structure

There are three bones of the os coxea (hip bone) that come together to form the acetabulum.
