DEMONSTRATION XV.

POSTERIOR TIBIO-FIBULAR REGION.

Dissection. Remove the skin from the posterior tibial region with
care so as not to destroy the communicans fibularis and tibialis forming
the external saphenous nerve. (See Fig. 242.) Note external saphenous
vein.

When the above superficial nerves and vein in the superficial fascia
have been traced and studied, clean and study the gastrocnemius
muscle; then cut its two heads near their origins and turn it down; do
not remove it.

Observe the plantaris muscle.

Study the soleus muscle. Then cut it at its origin and the tendon
of the plantaris and turn them down.

In cutting the origin of the soleus do not destroy any of the struc-
tures below.

Xote the tendo Achillis (tendo calcaneus), its formation and inser-
tion. Turn the tendo Achillis down to its insertion, with the gastroc-
nemius, soleus, and tendon of plantaris attached, but do not remove them.

Note the deep tibial fascia and internal annular ligament.

Trace down the posterior tibial artery and nerve, observing their rela-
tion to each other and to the surrounding muscles.
