Two special motions produced by the muscles of the forearm are the supination (anterior rotation) and pronation (posterior rotation) of the forearm and hand. Supination is produced by the biceps brachii of the upper arm and the supinator muscle of the forearm.uscles of the Arm and Hand. The muscles of the arm and hand are specifically designed to meet the bodyâs diverse needs of strength, speed, and precision while completing many complex daily tasks.
The brachialis is a muscle located underneath the lower part of the biceps brachii. This muscle originates at the distal half of the anterior humerus, or arm bone, and inserts at the coronoid process and the tuberosity of the ulna, or outer forearm bone.oth heads insert at the tuberosity of the radius, or inner forearm bone, and at the lacertus fibrosus of the fascia of the forearm. The biceps brachii acts to flex the elbow and supinate the forearm. You can emphasize the biceps brachii by utilizing a supinated, or underhand, grip while doing the biceps curl.
