the study of the structure & functions of the nervous system

controls & coordinates all other systems & makes them work harmoniously & efficiently

brain, spinal cord, & nerves

tissue that controls & coordinates all body functions

whitish cords made up of bundles of nerve fibers held together by connective tissue, through which impulses are transmitted

basic unit of the nervous system

the process or extension of a neuron by which impulses are sent away from the body of a cell

cell body, nucleus, dendrites & axon

controls sensation, muscles, glandular activity, & the power to think & feel

cranium

structure that connects the spinal cord to the brain

4. Cerebrum, cerebellum, diancephalon, brain stem

the part of the nervous system that controls the involuntary muscles; regulates the action of the smooth muscles, glands, blood vessels & heart.

nerve that affects the muscles of the mouth

lies at the base of the cerebrum & is attached to the brain stem; latin term for "little brain"

makes up the bulk of the brain & is located in the front, upper part of the cranium

Nerves that originate as the spinal cord, whose branches supply the muscles & scalp at the back of the head & neck

oval, bony case that protects the brain

affects the skin of the lower eyelid, side of nose, upper lip & mouth

tree like branching of the nerve fibers extending from a nerve cell; short nerve fibers that carry impulses toward the cell

located in the uppermost part of the midbrain; consists of 2 main parts: thalmus & hypothalmus

nerve that, with its branches, supplies the fingers & toes

a type of motor nerve that controls the motion of the neck muscles

artery that supplies blood to the lower region of the face, mouth, & nose.

chief sensory nerve of the face: controls chewing

located at the sides of the neck affecting the face,ears, neck, & parotid gland

located in the back of the head, affecting the scalp

affects the membrane & skin of the nose

nerve that affects the skin of the lower lip & chin

affects the point & lower sides of the nose

as part of the ANS, it operates under normal nonstressful situations

branch of the 5th cranial nerve that supplies the skin of the forehead, upper eyelids, i& nterior portion of scalp, orbit, eyeball, & nasal passage

affects the muscles behind the ear at the base of the skull

carry i pulses or messages from sense organs to the brain, where sensations of touch, cold, heat, sight, hearing, taste, smell, pain & pressure are experienced

chief motor nerve of the face, emerging near the lower par tof the ear

located at the base of the skull, affecting the scalp muscles behind the ear

affects the skin of the forehead, scalp, eyebrow, & upper lid

affects the skin between the eyes & upper side of the nose

part of the ANS that stimulates or speeds up activity & prepares the body for stressful situations "fight or flight"

affects muscles of the temple, side of forehead, eyebrow, eyelid, & part of the cheek

affects the pinky side of the arm & palm of the hand

affects the skin of the temple, side of forehead, & upper part of the cheek

an automatic nerve rxn to a stimulus that involves movm't of an impulsealong an efferent neuron to muscle, causing a rxn
