Q
3 Major Parts of a Neuron
A
1) Cell Body
2) Dendrites
3) Axon
2
Q
Dendrites
A
receives signals from other neurons
3
Q
Cell Body
A
processes information from dendrites
4
Q
Myelin sheath
A
firing processes faster (protective coding)
5
Q
Three basic neuron types
A
1) Sensory
2) Motor
3) Interneurons
6
Q
Four “basic” types of neurotransmitters
A
1) Acetylcholine
2) GABA
3) Dopamine
4) Serotonin
7
Q
Acetylcholine
A
- muscle actions, learning, memory
- first neurotransmitter found
8
Q
GABA
A
chief inhibitory function of the brain
9
Q
Dopamine
A
- voluntary movement
- reward anticipation - pleasure centers
10
Q
Serotonin
A
- regulation of sleep, mood, attention, learning
11
Q
Agonist
A
drug or substance that enhances or mimics action of neurotransmitter(s)
12
Q
Antagonist
A
drug or substance that blocks action of neurotransmitter(s)
