Which bone is the anteromedial part of the hip?
Anteriorly, the ramus of the ischium joins the inferior ramus of the pubis to form a bar of bone called the ischiopubic ramus that represents the inferior border of the obturator foramen. Ok, now, finally, there’s the pubis, which forms the anteromedial part of the hip bone.
What is the opening in the hip called?

The fovea capitis is a minor indentation on the medial side of the femoral head that serves as the site of attachment for the ligament of the head of the femur. This ligament spans the femur and acetabulum, but is weak and provides little support for the hip joint. It does, however, carry an important artery that supplies the head of the femur.
