The acetabulum is a rounded depression in the hip bone. It forms a socket which contains the ball-shaped head of the thigh bone, or femur, allowing it to rotate quite freely. Together, the acetabulum and the head of the femur form what is known as the hip joint. Acetabular fractures ...
In the hip joint, called the acetabulofemoral joint, the head of the femur or thigh bone inserts into a cavity in the pelvic bone called the acetabulum. This cavity is actually made up of three adjacent bones: the ischium, the ilium, and the pubis. Because circumduction of the hip ...

Bordered by the inferior gemellus muscle above and the adductor magnus muscle below, the quadratus femoris is the bottommost of the external rotators in the hip and the topmost of the adductor group in the thigh. It is a deep muscle, situated immediately beneath the large gluteus maximus, th...
damaged, the head of the femur depends on a small artery in theligamentof head of femur, or ligamentum teres. This ligament attaches to the acetabulum on one end and the fovea of head of femur on the other. The fovia is an ovoid dip in the femoral head, just slightly below its ...
A supra-acetabular crest helped prevent dislocation of the femur. The position of the knee joint, aligned below the acetabulum, made it possible for the whole hind limb to swing backwards and forwards. This unique combination of features gave dinosaurs what is known as a “fully improved gait...
The suction cups on the arms of an octopus are simply called suckers The internal wall is the infundibulum, and the cavity in the center is the acetabulum.
What part of the body is ilium? The Ilium. The ilium is the widest andlargest of the three parts of the hip bone, and is located superiorly. The body of the ilium forms the superior part of the acetabulum (acetabular roof). Immediately above the acetabulum, the ilium expands to form th...
What are the suction cups on an octopus called? The suction cups on an octopus' arms are calledsuckers. The internal wall is the infundibulum, and the cavity in the center is the acetabulum. Do octopus has tentacles? Barring a few exceptions,octopuses have eight arms and no tentacles, while...
