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 muscle is located in the upper arm. It lies underneath the biceps muscle. It acts as a structural bridge between the humerus, which is the bone of the upper arm, and the ulna, which is one of the forearm bones. The muscle is innervated by both the musculoskeletal nerve and the radial nerve.In some people, the muscle may appear doubled. Also called the brachialis anticus, its primary action is to flex the forearm muscles at the elbow.Due to its high contractile strength, the branchialis makes many arm and elbow movements possible. Such movements are important for the activities of daily life.he muscle is innervated by both the musculoskeletal nerve and the radial nerve. In some people, the muscle may appear doubled.
