Chapter 3 Flashcards
Neurons
Communication cells
React and respond to stimuli
Learn and Store information about the environment
Glial Cells
“Glue”
Types of Glial Cells
Astrocytes
Oligodendrocytes
Microglia
Astrocytes
Fill the space between neurons
Regulate how far neurotransmitters can spread
Oligodendrocytes
Produce myelin
Microglia
Remove debris from the nervous system
Parts of Neurons
Dendrites - Soma - Axon - Terminal buttons
Dendrites
Receive information from other neurons
Soma
Contains genetic information
Axon
Carries electrical impulse to transmit information
Terminal Buttons
Release neurotransmitters into synaptic cleft
Synapse
Site of transmission of electric nerve impulses between two neurons
Neurotransmitters
Chemical messengers in body
Glutamate
Excitatory neurotransmitter
GABA
Inhibitory neurotransmitter
Dopamine
Reward and Learning
Serotonin
Regulated eating, sleeping and emotions
Norepinephrine
Fight of Flight Stress response
Acetylcholine
Used by motor neurons
Nucleus
Group of cell bodies
