What is an isotonic contraction
Contractions of muscles with a change in muscle length
What is a concentric contraction
Muscle (muscle groups) contraction that results in shortening of a muscle.

TMJ Joint Structure
Made up of:
Motion at a joint occurs as a result of movement of one joint surface in relation to another.
Arthrokinematics is the term used to refer to the movement of joint surfaces. The movements
at the joint surfaces are described as slides (glides), sp

Types of Movement
All muscles exert their force by pulling between at least two points of attachment. The
movement that results from contraction is called the action of the muscle. Typically, one
attachment remains stationary and is called
