Divide body into LEFT and RIGHT
frontal PLANE
divide body into FRONT and BACK
Transverse Plane
Divide body into TOP and BOTTOM
Flexion
decrease the angle between bones of a join
Extension
Increasing the angle between bones of the joint
Agonists
the muscle that is responsible for the movement occurring
antagonist
the muscle that works in opposite to the agonist
articulating bones
bones that meet + make up the joint
concentric
muscle SHORTens under tension
eccentric
muscle LENGHTENS under tension
isometric
when muscle can contract without lengthening or shortening
