AL 129-1 a monkey, and decided to collect it. While he was writing it up, he noticed a few yards away a distal femur, the lower end of a thighbone. This was split between the condyles, or lumps making the knee joint. The other condyle lay next to it, and when he fitted them together and to the proximal tibia, the angle that the femur and tibia formed at the knee joint clearly showed that this was an upright walking hominid. This angular joint was in contrast to an ape, which has the femur and tibia forming a straight line. Tom Gray
Upper extremity of femur profound (deep) for the femoral artery. In the transition area between the head and neck is quite rough due to attachment of muscles and the hip joint capsule. Here the two trochanters, greater and lesser trochanter, is found. The greater trochanter is almost box-shaped and is the most lateral prominent of the femur. The highest point of the greater trochanter is located higher than the collum and reaches the midpoint of the hip joint. The greater trochanter can easily be felt. The trochanteric fossa is a deep depression bounded posteriorly by the intertrochanteric crest on medial surface of the greater
