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

tructure

There are three bones of the os coxae (hip bone) that come together to form the acetabulum. Contributing a little more than two-fifths of the structure is the ischium, which provides lower and side boundaries to the acetabulum. The ilium forms the upper boundary, providing a little less than two-fifths of the structure of the acetabulum. The rest is formed by the pubis, near the midline.

It is bounded by a prominent uneven rim, which is thick and strong above, and serves for the attachment of the acetabular labrum, which reduces its opening, and deepens the surface for formation of the hip joint. At the lower part of the acetabulum is the acetabular notch, which is continuous with a circular depression, the acetabular fossa, at the bottom of the cavity of the acetabulum. The rest of the acetabulum is formed by a curved, crescent-moon shaped surface, the lunate surface, where the joint is made with the head of the femur. Its counterpart in the pectoral girdle is the glenoid fossa.

In reptiles and in birds, the acetabula are deep sockets.

Etymology

The word acetabulum means "little vinegar cup", and was the Latin word for a small vessel for storing vinegar (see acetabulum). The word was later also used as a unit of volume, equal to roughly 270 ml.
