1
The primary cell that builds all the structures of the nervous system
Neuron
Name all structures of the entire nervous sytem
Brain, Spinal cord, and Nerves
What purpose is the purpose of the Myelin Sheath on an axon?
To speed up the electrical impulse
Name three neurotransmitters
Oxytocin, adrenaline, dopamine, GABA, melatonin, Norepinephrine, Serotonin, Acetylcholine,
This part of your brain controls balance, movement, and coordination.
cerebellum
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
This neurotransmitter is like the brains break
GABA
What part of the brain deals with music, art, creativity
Frontal lobe
what is the peripheral system made of?
Nerves
Name FOUR parts of a neuron
1- cell body (soma) 2- dendrites 3- axon 4- myelin sheaths 5- axon terminals 6- nodes of ranvier
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
People with ADHD have low ?
Dopamine
This part of your brain controls heartbeat, breathing, and other automatic body functions.
Brainstem
The central nervous system is made of these organs
brain and spinal cord
What does an axon terminal hold inside small vessicles?
neurotransmitters
Name the tiiiiiiny empty space between dendrites of one neuron and axon terminals of the connecting neuron
Synapes
The fight or flight neurotransmitters
Norepinephrine
This largest part of your brain helps you think, remember, speak, and make decisions.
cerebrum
An action potential travels along this structure until it reaches the axon terminal
the Axon
Name two positively charged ions travel in and out of a neuron to help impulses travel? Give their chemical abbreviations.
Potassium K
Na- Sodium
Name the gaps between the myelin sheaths on the axon?
nodes of ranvier
This “feel-good” chemical helps regulate mood, happiness, and sleep.
serotonin
Moves the right side of the body
Motor cortex
