[edit] Structure
The extensor digitorum brevis is found on the back of the foot. It arises with the extensor hallucis brevis muscle from the calcaneus bone; many consider these two muscles are a single common muscle.
The extensor digitorum brevis divides into three tendons, which insert on the second, third, and fourth middle phalanges.
[edit] Innervation
The extensor digitorum brevis is innervated by the deep fibular nerve (deep peroneal nerve).
[edit] Action
The extensor digitorum brevis help to extend the toes to which it attaches.
