The Nervns svralis (Figs. 128, 8j 129 s) runs downwards on the inner border of the M. cjastrocnemius and gives off :— (i) A twig {()") to the upper third of the muscle. (2) The Hamus cutaneiis mé- dius {es) is given off below the middle of the M. gastrocnemius ; it passes to the skin of the lower third of the leg. After giving off the latter branch, the N. siiralis runs downwards along- the inner aspect of the Tendo achillis to the Aponeurosis j)lan- taris of the sole of the foot as far as the calcar, and gives off:— Nerves of the leg and sole of the foot.
