Pronator quadratus muscle

The video tutorial discusses the pronator quadratus muscle, one of the three deep flexors of the forearm. It is located at the ventral forearm and is easy to palpate due to its proximity to the radius and ulna. The muscle originates from the distal ulna and attaches to the radius, giving it a square shape. It is innervated by the median nerve, specifically the anterior interosseous nerve. The pronator quadratus is responsible for pronation at the radial ulnar joint. The video encourages viewers to explore more anatomy resources on Kenhub.

Explain how the pronator quadratus contributes to the movement at the radial ulnar joint.
