What is the action of the triceps?
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 function of biceps and triceps?
For example, the biceps and triceps muscles work together to allow you to bend and straighten your elbow. When you want to bend your elbow, your biceps muscle contracts (Figure below), and, at the same time, the triceps muscle relaxes. The biceps is the flexor, and the triceps is the extensor of your elbow joint.

It’s really only visible when looking at the arms from the side, but will make your arms appear much larger when viewed this way.
What are the 3 heads of the triceps?
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.

Why is it called biceps and triceps?
