The triceps brachii (triceps) is a large, three-headed muscle of the upper arm. It consists of the long head, medial head and the lateral head.

All three heads together form a thick tendon which inserts at the olecranon of the ulna and additionally to the capsule of the elbow joint and antebrachial fascia. The triceps brachii forms the posterior compartments of our arms and is one of the strongest muscles of the arm, performing extension of the forearm, extension and adduction in the shoulder joint. It is innervated by the radial nerve.
