Insertion: lateral surface of the olecranon process and the superior part of the posterior ulna distally
Artery: deep brachial artery, recurrent interosseous artery
Nerve: radial nerve (C7, C8, and T1)

The anconeus muscle 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, while others consider it part of the posterior compartment of the forearm.

The Anconeus muscle can be easily palpated just lateral to the olecranon process of the ulna.
