Question

Quizplus · Accepted Answer

The triceps brachii is a powerful forearm extensor at the elbow joint. It has three heads: the long head, lateral head, and medial head, which work together to extend the elbow and provide stability to the joint. The brachialis, biceps brachii, and brachioradialis are also muscles that act on the elbow joint, but they primarily function as flexors rather than extensors.
