Sensory (afferent) neurons
Neurons that transmit nerve impulses fromm effector sites to the brain or spinal cord

Central nervous system
Consists of the brain and spinal cord and serves mainly to interpret information
Peripheral nervous system
Cranial and spinal nerves that spread throughout the body and serve to relay information from bodily orgams to the brain and from the brain to bodily organs
The ability of the nervous system to analyze and interpret sensory information to allow for proper decision making which produces the appropriate response
Golgi tendon organs
Organs sensitive to change in tension of the muscle and the rate of that change.
attach muscles to bones and provide the anchor from which the muscle can exert force and control bone and joint
are chemical messengers that transmit electrical impulses from the nerve to the muscle
The Muscular system
is a series of muscles that the nervous system commands to move the skeletal system
the functional unit of muscle that produces muscular contraction which consists of repeating sections of actin and myosin
the contraction of a muscle generated by the communication between the nervous system and muscular system
Portion of the skeletal system that consists of the skull, rib cage, and vertebral column
Joints that are held together by a join capsule and ligaments and are most associated with movement in the body
Type I Slow Twitch Fibers
Smaller in size, produce less force, slow to fatigue, long-term contractions
