Control center of nervous
system
Controls right side of
body, thought and
logic
Branch out from
spinal cord
Involuntary response
to stimuli
Reflex
Controls the left side
of the body, creativity
Changes in the
environment

Brain Stem
Nervous System Review
Dendrite
Carries impulse along nerve cell “tail”
Contains genetic material for neuron
Allows signal to transmit quickly down
axon/protective covering
Cell Body
Nucleus
First part of neuron to receive impulse
Houses the nucleus
Carries messages to the brain
Carries messages inside the brain
Carries messages to the body
Space between neurons and another
neuron or muscle or organ;
Ends of the Axons

Nervous System Review
Cerebellum Controls coordinates the muscles that you use for action such as
running, walking, or playing the piano. It also helps
control your balance and maintain posture.
Cerebrum Controls It regulates all your thoughts and actions. There are many sections of
the cerebrum that control what you hear, smell, how you move, how
you think, write, talk and express emotions.
Brain Stem involuntary actions such as breathing, heart rate, swallowing and
blinking.
Nervous System Review
Alzheimer’s DiseaseImpaired memory, thinking and behavior; sometimes
confused with aging
Multiple Sclerosis
Stroke
Chronic disease of CNS; Caused by destruction of
myelin sheath – means impulses (signals) slow down
or can’t get through
Brain cells die because of lack of oxygen; Brain attack; blood vessels can
clog (thrombosis) or burst (hemorrhage)
Cerebral Palsy Movement disorder; varies from not being able to
walk to being able to move more easily;
Parkinson’s Disease
Degenerative disease characterized by Tremors of the
limbs of the body
