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 brachioradialis muscle is located in the forearm. It enables flexion of the elbow joint. The muscle also assists with pronation and supination of the forearm. These two movements allow the forearm and hand to turn so that the palm faces up or down.The arms are the only part of the body with this ability.The muscle originates on the lateral supracondylar ridge of the humerus. This rough margin is located on the lower end of the humerus. From there, the brachioradialis travels the length of the forearm.It inserts into the distal radius, at the bony projection known as the radial styloid process.he arms are the only part of the body with this ability.
