Q

Brachioradialis OIAI?

A

Origin: humerus
Insertion: radius (near styloid process)
Action: flexes forearm at elbow; supinates and pronates forearm (back to neutral). When the forearm is pronated, it tends to supinate when flexed; when the forearm is supinated it tends to pronate. For this reason, it is known as the “beer drinker muscle.”
Innervation: radial nerve
