CNS
What is a system of nerves that connects the peripheral (outer) of the body to the CNS, or had both sensory and motor nerves.
PNS
What system function is to carry impulses/messages to and from CNS
PNS
What is the part of the nervous system that controls the involuntary muscles, regulates the action of smooth muscles, glands, blood vessels, heart and breathing
ANS
What is the largest and most complex mass of nerve tissue in the body.
Brain

12, cranial nerves
What connects the spinal cord to the brain.
Brain stem
The brain stem is involved in regulating vital functions such as
Breathing, heartbeat and blood pressure
What is a continuation of the brain stem and originates in the brain, extends down to the lower extremity of the trunk and is protected by the spinal column.
Spinal cord
How many pairs of spinal nerves extending from the spinal cord
31
What are the whitish cords, made up of bundles of nerve fibers held together by connective tissue, through which impulses are transmitted.
Nerves
What originate in the brain and spinal cord and their branches extend to all parts of the body.
Nerves
What nerves carry impulses or messages from the sense organs to the brain where sensations are experienced.
Sensory nerves
Sensory nerve endings are called
Receptors
Where are receptors located
Close to the surface of the skin.
What nerves carries impulses from the brain to the muscles or glands. These transmitted impulses produce movement.
Motor nerves
What is a autonomic nerve reaction to a stimulus that involves the movement of an impulse from sensory receptor along the sensory nerve to the spinal cord and a responsive impulses back along a motor neuron to a muscle, causing a reaction
Reflex
Sensory nerves are also known as
Afferent
Motor nerves are also known as
Efferent
