Next in order are the thigh-bones, the heads of which are even more globular than those of the arm-bones, although those are the most globular of the other bones; below there are two processes, one directed forward, the other backward; after this the bones are hard and marrowy and convex on the outer side, and they are again enlarged at their lower ends also. The upper ends are inserted into hollows of the hip-bones, as the arm-bones into the shoulder-bones; then these tend gently downwards and inwards in order that they may support the upper parts of the body more evenly. But the heads at the lower end have a hollow in between, that the leg-bones may be more easily fixed into them. Their juncture is covered by a small, soft, cartilaginous bone, called the knee-cap. This bone, which floats freely and is not attached to any other bone, but held in place by flesh and sinews, is turned slightly towards the thigh-bone and protects the joint in all movements of the legs.
