Overview of Anatomy and
Physiology
• Nerve and blood supply

Blood vessels provide a constant supply of oxygen
and nutrition, and nerve cells/fibers supply a constant
source of information




Muscle stimulus—when a muscle cell is adequately
stimulated, it will contract
Muscle tone—skeletal muscles are in a constant state
of readiness for action
Types of body movements—flexion, extension,
abduction, adduction, rotation, supination, pronation,
dorsiflexion, and plantar flexion
