Autonomic Nervous

System

Part of the peripheralnervous system. Controlsinvoluntary functions of thebody.

The largest and highestsection of the brain responsible

for reasoning, thought, judgment, speech, sensation,sight, smell, hearing andvoluntary body movement.

Central Nervous System

Consists of the brain andspinal cord

Cerebellum

Responsible for musclecoordination, balance,posture, and muscle tone

Cerebrospinal fluid

Clear fluid that acts as ashock absorber to protectthe brain and spinal cord.

Hypothalamus

Regulates and controls theautonomic nervous system,temperature and appetite.

Medulla Oblongota

The lowest part of thebrainstem that regulatesrespiration, swallowing,coughing, and blood

pressure

Meninges

Three membranes thatcover and protect the brainand spinal cord.

Midbrain

Responsible for conductingimpulses between brainparts and for certain eyeand auditory reflexes.

Nerves

A combination of manynerve fibers located outsidethe brain and spinal cord.

Nervous System

A complex, highly organizedsystem that coordinates allthe activities of the body.

Neuron

Nerve Cell

Parasympathetic

A division of the autonomic

nervous system.Counteracts the actions ofthe sympathetic system.Slows heart rate, decreasesrespirations, lowers BP, and

increases activity indigestive tract.

Peripheral NervousSystem

Consists of the nerves andhas two divisions: somaticnervous system andautonomic nervous system.

Responsible for conductingmessages to other parts ofthe brain for chewing,tasting, saliva production

and assisting withrespiration.

Somatic NervousSystem

Carries messages betweenthe CNS and the body

Spinal Cord

Continues down from themedulla oblongata and endsat the first or second lumbarvertebrae. Responsible for

carrying messages.

Sympathetic

Prepares the body for timesof emergency. Increasesheart rate, respiration, andblood pressure, and slows

activity in the digestive tract

Thalamus

Acts as a relay center anddirects sensory impulses to

the cerebrum

Ventricles

Hollow spaces that connectwith each other

Amyotrophic lateralsclerosis (Lou Gehrig’s

disease) a chronic,degenerative neuromuscular

disease

Multiple Sclerosis. A

chronic, progressive

disabling condition

Cerebrovascular Accident.Occurs when the blood flow

to the brain is impaired.

Cerebral Palsy.Disturbance in voluntary

muscle action and is causedby brain damage

“fight or flight”

What happens to your bodyduring the sympathetic

nervous system response toan emergency
