Agonist
A muscle that causes or controls joint motion through a specified plane of motion; also known as a mover


Antagonist
A muscle usually located on the opposite side of a joint from the mover )agonist) and having the opposite action. The antagonist must lengthen when the mover contracts and shortens. Aponeurosis


Aponeurosis
A broad, flat sheet of fibrous connective tissue


Concentric action
A contraction in which the muscle shortens with tone because its contractile force is greater than the opposing force at the attachments of the muscles. Concentric contractions are contractions of a mover (agonist) when it creates the movement of a body part.


Contractility
The ability of a muscle to shorten forcibly with adequate stimulation. This property sets muscle apart from all other types of tissue.


Deep fascia
A coarse sheet of fibrous connective tissue that binds muscles into functional groups and forms partitions, called intermuscular septa,...
