Extensor Digiti Minimi:The extensor digiti minimi muscle is thought to originate from the extensor digitorum muscle. In some people, these two muscles are fused together. Anatomically, the extensor digiti minimi muscle lies medially to the extensor digitorum.
Origin: Originates from the lateral epicondyle of the humerus.
Insertion: It attaches, with the extensor digitorum tendon, into the extensor hood of the little finger.
Function: Extends the little finger, and contributes to the extension of the wrist.
Nerve supply: Radial nerve (deep branch).
