2 THE MUSCULAR SYSTEM Muscle Tissue - refers to all the contractile tissues of the body; skeletal, cardiac, and smooth muscle. Muscular System - refers to the skeletal muscle system: the skeletal muscle tissue and connective tissues that make up individual muscle organs, such as the biceps brachii muscle. GENERAL PRINCIPLES This chapter is devoted to the description of the major named skeletal muscles. Tendons – Attach muscle to bones and other connective tissues. Aponeurosis – A very broad tendon. Origin (head) – Is normally the of the muscle attached to the more stationary of the two bones. Insertion – Is the end of the muscle attached to the bone undergoing the greater movement. Belly – Is the largest portion of the muscle, between the origin and the insertion. Agonist – Is a muscle causing an action when it contracts. Antagonist – Is a muscle working in opposition to the agonist, moving a structure in the opposite direction. Synergists - Are muscles that work together to cause a movement. Prime mover – Is a muscle, among a group of synergists, that plays the major role in accomplishing the desired movement.
