What are the pronator muscles?

Pronator teres is a fusiform muscle found in the anterior forearm. It belongs to the group of superficial flexors of the forearm, together with flexor carpi radialis, palmaris longus, flexor digitorum superficialis and flexor carpi ulnaris muscles. Pronator teres is the most lateral muscle of this group.

How many pronator muscles are there?

Which muscle is the prime extensor of the elbow joint?

The muscles on the posterior (back) of the arm are extensors. The prime mover of elbow extension is the triceps brachii muscle, and is assisted by the much smaller anconeus muscle. All anterior (front) arm muscles cause elbow flexion.
