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 a muscle in the upper arm that flexes the forearm at the elbow joint. Origin and Insertion: The brachialis muscle originates from the lower half of the anterior humerus, near the insertion of the deltoid muscle. The brachialis muscle is located underneath of the biceps brachii muscle. It is inserted into the tuberosity on the anterior surface of the coronoid process of the ulna.
