Muscles of tlic hinder Extremity. — The thick flexor of the thigh (fig. 207, 31), repre- senting the iliacus interims, arises broadly from the whole inner surface of the os ilei passes over the os pubis, and is inserted into the femur below its middle. The long ex- tensor and adductor of the thigh (32) arises from the third and fourth caudal vertebra, and is inserted into the posterior aspect of the femur about its middle. The long abductor of the leg (fig. 207, 33) arises from the external surface of the os ilei, and is inserted into the tibia about its lower third. The anterior abductor of the thigh (figs. 207 and 208, 34) arises from the anterior and internal surface of the os ilei, and is inserted into a broad tendinous expansion that covers the knee-joint. The thin flexor of the leg (fig. 208, 36) arises from the inferior lateral surface of the os ilei, and is inserted into the outer part of the head of the tibia. A long muscular slip ( and 208, 37) arises from the transverse processes of the third and fourth vertebrae of the tail, and is inserted into the back of the thigh bone. The chief muscle of the sole of the foot (38) arises from the side of the sacrum, and is inserted into the thick fascia of the sole. The other muscles of the foot are an extensor and abductor of the tarsus (39), which arises from the upper end of the tibia, and is inserted into the outer surface of the tarsal bone. An extensor longus digitorum pedis (40) arising from the fascia of the knee, and the anterior surface of the
