Nervous System 1
The primary cell that builds all the structures of the nervous system
2
What is the central nervous system made of?
Brain and spinal cord
What does the Somatic divison of the nervous system control?
Voluntary movements of the body
What is the peripheral system made of?
Nerves that branch off from the spinal cord.
What does PNS stand for?
Peripheral nervous system
What does CNS stand for?
Central Nervous System
The division of your peripheral nervous system that is made up of the nerves that control involuntary body responses and functions.
Autonomic nervous sysytem
A spontaneous response of the bod to a stimulus is known as
Reflex
Name the function of the neurotransmitter adrenaline
Stress response, fight or flight, excites nervous system, fear response
Two subdivisions of the Autonomic Nervous System--and the function of each
Sympathetic "Fight of Flight" Parasympathetic Division- "rest and digest"
What is a super long nerve column made up of tissue, technically an organ?
Spinal cord
What structure functions like a highway and transmits nerve impulses from the body to the brain and from the brain to the body?
The Spinal Cord
What does a dendrite do?
Receives neurotransmitters from another neuron's axon terminal
Which part of the brain would you find sensory reactions like heat, pain, cold
parietal lobe
The central nervous system is made of these organs
brain and spinal cord
What is the largest part of the brain?
Cerebrum
What are the parts of the neuron
Dendrites, axon, cell body
This type of neuron carries messages from the CNS back out to muscles in response to a sensory impulse.
Motor neurons
What are two ways to prevent problems to your nervous system?
Eat a well balanced (whole food) diet, wear a helmet, wear a helmet, stay away from drugs, stay away from alcohol.
The messages travel along this structure until it reaches the nerve terminals
the Axon
The_________________________________ nervous system is responsible for slowing the body back down (i.e. slowing down heart rate)
Parasympathetic
Name the gaps between the myelin sheaths on the axon
Nodes of Ranvier
Name the lobes of the brain
Frontal, parietal, temporal ,occipital
What is any other part of the nervous system that is not the brain or spinal cord?
Peripheral Nervous System (PNS)
