DHO CH 7:6

autonomic nervous system

contains the sypathetic & parasympathetic nervous systems: controls involuntary actions

brain

The part of the central nervous system that is located in the skull and controls most functions in the body

central nervous system

consists of the brain and spinal cord

cerebellum

posterior part of the brain that coordinates muscle movements and maintains balance

cerebrospinal fluid

a clear, colorless, and watery fluid that flows throughout the brain and around the spinal cord

cerebrum

the largest and highest section of the brain, concerned with reasoning, the senses, speech, and voluntary body movement

diencephalon

The part of the brain located between the cerebrum and the midbrain. Its main structures consist of the thalamus, hypothalamus, and pineal gland.

hypothalamus

regulates and controls many body functions

medulla oblongata

lower part of the brain stem controls breathing and heart beat,

meninges

membranes that cover the brain and the spinal cord

midbrain

the small part of the brain above the pons that arouses the brain, integrates sensory information, and relays it upward

nerves

tissue that conduct impulses

nervous system

the sensory and control apparatus consisting of a network of nerve cells

neuron

a nerve cell

parasympathetic

the branch of the nervous system that automatically calms us down when the reason for arousal has passed

peripheral nervour system

the sensory and motor neurons that connect the central nervous system to the rest of the body

pons

A portion of the brainstem that relays information between the cortex and medulla, regulates sleep, and carries some motor and sensory information from the head and neck.

somatic nervous system

The branch of the PNS that carries information from the central nervous system to regulate voluntary control of skeletal muscles.

spinal cord

column of nervous tissue from the brainstem through the vertebrae; responsible for nerve conduction to and from the brain and the body

sypathetic

part of the nervous system that controls the "flight or fight" response

thalamus

brain structure that receives messages from the sense organs and relays the information to the proper region of the cerebrum for further processing

ventricles

the lower two chambers of the heart
