What Is The Acetabulum? - Dr. Mullis (VIDEO)

Dr. Mullis:
The acetabulum is the socket part of the ball and socket of your hip joint. So, the acetabulum is made up by several bones of the pelvis. We talked before about all the bones that make up the entire pelvic ring. On one side you have the pubis, the ischium, and the ilium, and on that side that will make up the acetabulum or socket joint.

And then of course you have a pubis, ischium, and ilium on the other side, and another socket joint, and then, where those bones come together in the back at the sacrum, that makes up the entire pelvic ring. So the acetabulum really is a part of the pelvis, but is also a part of the hip joint.
