What are EDL muscles?
Extensor digitorum longus (EDL muscle) is a feather-like muscle of the anterior (extensor) compartment of leg. Since all these muscles cross the dorsal aspect of the ankle joint, their common function is dorsiflexion of the foot.
What is EDB muscle?

Do mice have biceps?

What is the function of the extensor digitorum?
Function. Primarily, the extensor digitorum communis extends medial four digits at the metacarpophalangeal joints and secondarily at the interphalangeal joints. It also acts to extend the wrist joint.
What is extensor digitorum brevis?
Extensor Digitorum Brevis is one of the intrinsic muscles on the dorsum of the foot. It arises from the upper and lateral surface of the calcaneous, the floor of tarsal sinus, the talocalcaneal ligament, and the stem of the inferior extensor retinaculum.
What is peroneal EDB?
Abstract. The accessory deep peroneal (ADPN) nerve has been regarded as an anomalous nerve derived from the superficial peroneal nerve or its branch and supplies motor innervations for extensor digitorum brevis (EDB) and sensory innervations for the lateral part of the ankle and foot regions.
What is the difference between the extensor digitorum brevis and the extensor digitorum longus?
The lack of direct bony attachments confines extensor digitorum brevis to help other muscles perform their actions. Most importantly, it assists extensor digitorum longus to extend the second, third and fourth toes at the corresponding distal interphalangeal joints.
