Fasciculi to the Posterior Tibial Muscles.—This fasciculus is composed of numerous branches, which are detached together from the sciatic nerve on its passage between the gastrocnemii muscles, in the form of a thick short trunk. The muscles of the superficial layer—the gastro- cnemii, perforatus, and the thin fleshy band, improperly designated the small plantaris by Veterinarians—receive ramuscules which are remarkable for their THE OR Posterior Crural Muscles.— This branch is thick and short; it arises from the bend formed by the great femoro-popliteal nerve at the gemini muscles, and soon divides into several ramifications which are dis- tributed to the short portion of the triceps cruris, the middle and inferior parts of the semitendinosus, and into the semimembranosus. Some of the filaments destined to the latter muscle pass between it and the great adductor of the thigh, in which they partly terminate (Fig. 356,12). 4. External Saphenous Nerve. —This branch commences at from 2 to 6 inches from the point where the great sciatic nerve dips between the gastrocnemii muscles. It is placed on the external gastrocnemius, and descends underneath the special apo- neurotic layer covering that muscle, to the origin of the tendon of the hock. It then receives its acce
