Anconeus muscle

Anconeus muscle
Anconeus muscle
	Back of right upper extremity. (Anconeus labeled at bottom center.)
	Posterior surface of the forearm. Superficial muscles. (Anconeus visible at center right.)
Details
Origin	Lateral epicondyle of the humerus proximally
Insertion	Lateral surface of the olecranon process of the ulna and the superior proximal part of the posterior ulna
Artery	Deep brachial artery, recurrent interosseous artery
Nerve	Radial nerve (C5, C6, C7, C8, and T1)
Actions	It is partly blended in with the triceps, which it assists in extension of the elbow. It also stabilizes the elbow during pronation and supination and pulls slack out of the elbow joint capsule during extension to prevent impingement.

The anconeus muscle (or anconaeus/anconæus) is a small muscle on the posterior aspect of the elbow joint.

Some consider anconeus to be a continuation of the triceps brachii muscle.^[1]^[2]^[3] Some sources consider it to be part of the posterior compartment of the arm,^[4] while others consider it part of the posterior compartment of the forearm.^[5]

The anconeus muscle can easily be palpated just lateral to the olecranon process of the ulna.^[6]
