Preferred Label : acetabular part of hip bone;
Uberon definition : The acetabulum is a concave surface of the pelvis. The head of the femur meets with
the pelvis at the acetabulum, forming the hip joint. 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.[WP,unvetted].;
Uberon synonym : acetabular region; acetabulum;
Uberon Homology note : During the transformation from the osteolepiform fins to tetrapod limbs, the appendages
and girdles underwent a number of radical changes. The pelvic girdle became a weight-bearing
structure by evolution of an ischium, a full mesio-ventral contact between the two
sides of the girdle, an ilium, and a contact between the vertebral column and the
girdle through a sacral rib. Fore- and hindlimbs shifted laterally by reorientation
of the glenoid and the acetabulum.[well established][VHOG];
Uberon Taxon note : In reptiles and in birds, the acetabula are deep sockets.;
