The triceps, also 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. It is the muscle principally responsible for extension of the elbow joint (straightening of the arm).
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.
Where are the three heads of the triceps?
The tricep muscle located on the back of the arm is a single muscle unit with three heads, the medial, lateral and long head. The long head is biarticular, originating at the scapula and inserting on the elbow.
Why does triceps have 3 heads?
Conclusions. Each head of the triceps brachii has a different pattern of force and activity during different shoulder elevations. The long head contributes to elbow extension more at shoulder elevation and the medial head takes over at 90° and above of shoulder elevation.
What does each head of the triceps do?
Conclusions: Each head of the triceps brachii has a different pattern of force and activity during different shoulder elevations. The long head contributes to elbow extension more at shoulder elevation and the medial head takes over at 90° and above of shoulder elevation.
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.
How do you target the heads of the triceps?

Which head of the triceps is least active at the elbow?
The TB’s elbow extensor work is enhanced, to a small degree, by the mon-articular anconeus [4-6]. Salmons  indicates that the medial head is involved in all forms of elbow extension, while the long and lateral heads become active only when the elbow is extended against resistance.
What exercises work the different tricep heads?
