Triceps brachii (TB) is the largest arm muscle responsible for elbow extension and horizontal arm abduction and also participates as an antagonist muscle during elbow flexion (Hussain et al., 2018). This muscle comprises three heads, namely, the long, lateral and medial heads.

Do dips hit all three tricep heads?
As Coach Mike Robertson notes, “A basic rule of thumb should be this: If it uses more weight, it’s probably a more effective exercise. For the triceps, that means dips and close-grip bench presses.” Unlike some triceps movements, dips hit every head of the triceps: the long, medial, and lateral.

What joint does the triceps Brachii cross?
The triceps crosses two joints, the shoulder and elbow joints. The primary action of the triceps brachii is extension of the elbow. It is the strongest extensor of the elbow. All three heads are responsible for this action.
What is the head of the triceps brachii muscle?
The long head of the Triceps brachii is one of three heads that make up the muscle. It descends between teres minor and major, dividing the wedge-shaped interval between them and the humerus into triangular and quadrangular spaces.
What nerve root controls the triceps?
The radial nerve is a nerve in the human body that supplies the posterior portion of the upper limb. It innervates the medial and lateral heads of the triceps brachii muscle of the arm, as well as all 12 muscles in the posterior osteofascial compartment of the forearm and the associated joints and overlying skin.
