Dissection of plantar aspect of left foot

Tendons of flexor digitorum longus; lumbrical muscles; quadratus plantae muscle; medial and lateral plantar nerves

The flexor digitorum brevis has been divided close to its origin (10) to permit the muscle to be reflected distally. A branch (12) of the nerve supplying the muscle (see view 200-2) can be traced to the lateral parts of the muscle belly.
