A ctions.—Flexes the foot dorsally and extends the four lesser toes. 204 MYOLOGY Nerve Supply.—Deep peroneal nerve (L. 4, 5, S. i). The m. peroneus tertius arises with the preceding from the medialsurface of the shaft of the tibia and the intermuscular septum and isinserted into the dorsal surface of the base of the fifth metatarsalbone. Actions.—Flexes the foot dorsally and raises the lateral margin ofthe foot.

Fig. 157.—The muscles of the ventral surf ace of the lower leg and of the dorsum of the transverse crural ligament has been removed. (SoboUa and McMurrich.) The m. extensor hallucis longus rises from the middle two-thirdsof the medial surface (ventral part) of the fibula and from the inter-osseous membrane. The tendon passes over the dorsum of the footand is inserted into the base of the distal phalanx of the great toe. Actions.—Extends the great toe &nd flexes the foot dorsally. Nerve Supply.—Deep peioneal nerve. The m. extensor digitorum brevis arises from the dorsal surface ofthe calcaneus and from the lig. cruciatum cruris. Its four tendonsare inserted into the four inner toes. The innermost tendon is in-serted into the base of the first phalanx of the great toe while the THE DORSAL MUSCLES OF THE LEG 20S Other three tendons join the long extensor tendons of the next threetoes. Action.—Extends the four inner toes. Ne
