Muscle movement: Most skeletal muscles work in groups:
 Agonists - muscles primarily responsible for an action due to their contraction.
Antagonists - muscles that relax to smooth the action of the agonists.Directions of move-
ment:
 Flexion - brings a body part forward.
 Extension - moves a body part to the rear.
 Abduction - moves an appendage laterally from the midline.
 Adduction - moves an appendage toward the midline.
 Circumduction - movement of an appendage in a circle around a joint.
 Pronation - rotating the palm of the hand downward.
 Supination - rotating the palm of the hand upward.
 Inversion - turning the toes of the foot inward.
Eversion - turning the toes of the foot outward.
