(Great tibio-phalangeus—Leyh.} Extent—Situation—Direction—Com- position.—Extending from the superior extremity of the leg to the third phalanx,, and situated behind the tibia and foot,, the direction of which it follows, this muscle is composed of a muscular body and a tendon. Form, Structure, and Attachments of the muscular portion.—This is thick and prismatic, and incompletely divided into two portions—an internal,^ and an ex- ternal,^ which is the most voluminous. It is attached : 1. To the posterior face of the tibia, on the linear imprints which occupy the inferior triangular surface. 2. To the supero-external tuberosity of the same bone. 3. To the peroneus. 4. To the interosseous ligament uniting that bone to the tibia. Direction and Attachments of the tendon.—The tendon commences above the inferior extremity of the tibia, where it is usually double, each muscular portion being succeeded by a tendon, the volume of which is in harmony with the size of the muscle from which it proceeds. The single tendon resulting from the union of these two primary ones, enters the groove formed by the inner face of the os calcis, where it is retained by a fibrous arch which transforms this channel into a perfect.
