The extensor digitorum communis is a superficial extensor muscle located in the posterior compartment of the forearm. [1] . It shares a common synovial tendon sheaths along with other extensor muscles which helps to reduce friction between the …

The extensor digitorum muscle (also known as extensor digitorum communis) [2] is a muscle of the posterior forearm present in humans and other animals. It extends the medial four digits of the hand. Extensor digitorum is innervated by the posterior interosseous nerve, which is a branch of the radial nerve. [3]

Extensor Hoods are an elaboration of the extensor digitorum comunis (EDC) tendon on the dorsum of each phalanx. The extensor indicis (EI) and the extensor digiti minimi (EDM) insert into the extensor hoods of the second and fifth digits, respectively.

Jun 21, 2024 · The extensor digitorum communis muscle (EDC), the principal extensor of the medial four digits of the hand, occupies much of the posterior surface of the forearm. It’s located in the superficial compartment of the posterior forearm.
