Anequalized motion of thc body is seldom seen in walking ;the tread of the left foot is usually less firm, a greaterpush is made by it, and the toe is not so much turnedout as in the right. Exercise and training of the leftextremities are especially necessary to compensate for any-thing lacking in natural Fig. 30 ACADEMIC PHYSIOLOGY. CHAPTER V. THE SKELETON (concluded^). HYGIENE OF THE BONES. 1. The Lower Extremities. — The lower extremities are,like the upper extremities, long and jointed; they arecommonly known as the legs, and are united to the lowerend of the spinal column by means of the bones of thehips. 2. Each lower extremity is divided into a hip, thigh, leg,ankle, and foot; together the lower extremities containsixty-two bones, one bone entering into the formation ofeach hip, one in the thigh, three in the leg, seven in theankle, and nineteen in the foot. 3. The hip-bones are also called the innominate bones(Lat. in, not; and nomen, a name) ; each contains a deep,cup-like cavity on the external surface, into which therounded head of the thigh bone fits to form the broad, bony basin formed by the hip-bones and thesacrum is called the pelvis, which supports the inter-nal organs of the lower part of the trunk
