⩥nervous system functions. Answer: 1. sensory: changes in the
environment
2. integrative: analyze and interpret
3. motor: the neuromuscular response


⩥Central nervous system (CNS). Answer: brain and spinal cord;
coordinates activity of the body


⩥Peripheral nervous system (PNS). Answer: nerves connecting the CNS
to the rest of the body and environment.


subdivisions:
- somatic
- autonomic
- parasympathetic
- sympathetic

,⩥Somatic. Answer: - apart of the PNS
- serves outer areas of the body and skeletal muscle; voluntary


⩥Autonomic. Answer: - apart of the PNS
- involuntary systems (e.g., heart, digestion).


subdivisions:
- parasympathetic
- sympathetic


⩥Parasympathetic. Answer: - apart of the autonomic system of the PNS
- decreases activation during rest and recovery.


⩥Sympathetic. Answer: - apart of the autonomic system of the PNS
- increases activation to prep for activity.


⩥neuron. Answer: functional unit of the nervous system.


- motor (efferent)
- sensory (afferent)

,⩥motor neurons. Answer: - efferent
- transmit nerve impulses from CNS to effector sites.


⩥sensory neurons. Answer: - afferent
- respond to stimuli; transmit nerve impulses from effector sites to CNS.


⩥mechanoreceptors. Answer: sense distortion in body tissues.


⩥Joint receptors. Answer: respond to pressure, acceleration, and
deceleration of joints.


⩥Golgi tendon organs (GTO). Answer: sense changes in muscular
tension.


⩥Muscle spindles. Answer: sense changes in muscle length.


⩥Tendons. Answer: connect muscle to bone; provide anchor for muscles
to produce force.


⩥Fascia. Answer: outer layer of connective tissue surrounding a muscle.


⩥Fascicles. Answer: bundle of individual muscle fibers.

, ⩥Muscle fiber. Answer: cellular components and myofibrils encased in a
plasma membrane.


⩥Sarcomere. Answer: produces muscular contraction; repeating sections
of actin and myosin.


⩥Sliding filament theory. Answer: thick and thin filaments slide past one
another, shortening the entire sarcomere.


⩥Type I muscle tissue. Answer: - slow twitch
- smaller size; fatigue slowly.


⩥Type II muscle tissue. Answer: - fast twitch
- larger size; quick to produce maximal tension; fatigue quickly.


⩥Motor unit. Answer: one motor neuron and the muscle fibers it
connects with.


⩥Neural activation. Answer: contraction of a muscle generated by neural
stimulation.


⩥Neurotransmitters. Answer: chemical messengers that transport
impulses from nerve to muscle.
