PELVIC LIMBS. 79 deficiency to the bottom of the cup. The deficiency, incisura acetabuli, or acetabular notch (d'), is closed naturally by a ligament, and the groove gives origin to the ligament (liga- mentum teres) which attaches the head of the femur. Femur (Fig. 56).—The femur is the proximal bone of the posterior extremity. It consists of enlarged proximal and distal ends connected by a nearly cylin- J^- drical shaft. The proximal end presents on its medial side a hemispherical head (a) which fits into the acetabulum. It is supported by a neck (/;) which is con- tracted near the head and expanded dorso- ventrally where it joins the remainder of the bone. The medial surface of the head presents near its ventral border a depres- sion (c) for the insertion of the round liga- ment of the femur. Ventrad the articular surface of the head extends as an acute projection onto the shaft, so that the whole articular surface appears somewhat pear- shaped. On the lateral side of the proxi- mal end opposite the head is a projecting mass, the great trochanter (d), forming the end of the shaft. On the medial side of the great trochanter at its junction with the neck is a deep fossa, the trochanteric fossa or digital fossa (c) for the insertion of muscles. the great trochanter a ridge, the inter- a, head; b, neck; c, de- trochanteric line (/), is continued distad, P'^^^f"" fc"- 'o""^!
