APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The triceps, or triceps brachii (Latin for “three-headed muscle of the arm"), is a large muscle on the back of the upper limb of many vertebrates. It consists of 3 parts: the medial, lateral, and long head.

Detailed explanation-2: -The triceps brachii is a large, thick muscle on the dorsal part of the upper arm. It often appears as the shape of a horseshoe on the posterior aspect of the arm.

Detailed explanation-3: -The triceps Brachii (TB) is a powerful extensor muscle of the upper extremity. It has been described as a single muscle unit with three heads (medial, lateral, and long heads), 2 and a cadaver study found that the medial head of the TB was attached to the olecranon by a deeper separated tendon than the other heads.

Detailed explanation-4: -The triceps brachii is a muscle located in the upper arm. This muscle gets its name because it has three muscle heads (tri means three). The ‘head’ of a muscle is a point of origin.
