ANATOMY

Detailed explanation-1: -The triceps brachii is a large, thick muscle on the dorsal part of the upper arm. It often appears in the shape of a horseshoe on the posterior aspect of the arm. The primary function of the triceps is the extension of the elbow joint.

Detailed explanation-2: -The superior portion of the long head of triceps is covered by the posterior border of the deltoid muscle. The long head of triceps can be palpated as an elevation parallel and medial to the posterior border of the deltoid muscle when the elbow is extended.

Detailed explanation-3: -Tricep tendonitis often occurs when repetitive or prolonged activities begin to strain the triceps tendon. Some activities that may lead to irritation of the triceps tendon include repetitive pushing movements or straightening the elbow against resistance, such as performing push-ups, dips, or lifting heavy weights.

Detailed explanation-4: -The long head of the triceps is the largest part of your triceps and is found running down the back of your arm. The long head is different from the medial and lateral heads, as it crosses the shoulder joint and assists in shoulder extension.

Detailed explanation-5: -Your triceps is the muscle along the back of your upper arm that helps you extend your elbow and straighten your arm. The “tri” in the triceps comes from the fact that the muscle has three heads or points of origin: the long head, the lateral head, and the medial head.
