What muscles cause pronation of the forearm?

A tough membrane of connective tissue, called the interosseous membrane, keeps the forearm bones bonded during pronation and supination. The main muscles enabling pronation of the upper limb are pronator teres, pronator quadratus, and brachioradialis muscles.

What happens during supination of the forearm?

Forearm supination is rotation of the radius so the palm faces posteriorly (back to the anatomical position). It occurs primarily at the proximal radioulnar joint by rotation of the radial head against the radial notch of the proximal ulna, held in by the annular ligament. It is the opposite of forearm pronation.
