The acetabulum (/ ˌ æ s ɪ ˈ t æ b j ə l ə m /; [1] pl.: acetabula), also called the cotyloid cavity, is a concave surface of the pelvis. The head of the femur meets with the pelvis at the acetabulum, forming the hip joint. [2] [3]

It exits the pelvis inferior to the piriformis muscle, [1] between piriformis muscle and coccygeus muscle. [citation needed] It then descends in the interval between the greater trochanter of the femur and tuberosity of the ischium. It is accompanied by the sciatic nerve and the posterior femoral cutaneous nerves, and covered by the gluteus ...
It passes down along the brim of the pelvis and gives off two large branches - the "inferior epigastric artery" and a "deep circumflex artery." These vessels supply blood to the muscles and skin in the lower abdominal wall. The external iliac artery passes beneath the inguinal ligament in the lower part of the abdomen and becomes the femoral ...
The other two hip bones, the ischium and the pubis, extend ventrally down from the ilium towards the belly of the animal. The acetabulum, which can be thought of as a "hip-socket", is an opening on each side of the pelvic girdle formed where the ischium, ilium, and pubis all meet, and into which the head of the femur inserts. The orientation ...
The anterior superior iliac spine refers to the anterior extremity of the iliac crest of the pelvis. This is a key surface landmark, and easily palpated. It provides attachment for the inguinal ligament, the sartorius muscle, [1] [4] and the tensor fasciae latae muscle. [2] [3]
In primitive tetrapods, the main points of muscle attachment along the femur are the internal trochanter and third trochanter, and a ridge along the ventral surface of the femoral shaft referred to as the adductor crest. The neck of the femur is generally minimal or absent in the most primitive forms, reflecting a simple attachment to the ...
Above, the linea aspera is prolonged by three ridges. The lateral ridge is very rough, and runs almost vertically upward to the base of the greater trochanter.It is termed the gluteal tuberosity, and gives attachment to part of the gluteus maximus: its upper part is often elongated into a roughened crest, on which a more or less well-marked, rounded tubercle, the third trochanter, is ...
