Chapter 2: The biological perspective Flashcards
basic cell that makes up the nervous system and receives and sends messages within the system
neuron
receives messages from other neurons; receive signals
dendrites
carry signals away to other cells
axon
cell body of the neuron; responsible for maintaining the life of the cell
soma
rounded areas at the end of the branches at the end of the axon; responsible for communicating with other nerve cells
axon terminals
chemical found in the synaptic vesicles which, when released, has an affect on the next cell; released to cause behaviors
neurotransmitters
space between one neurons axon and dendrites
synapse
holes in the surface of the dendrites or certain cells of the muscles and glands
receptor sites
which neurotransmitter is your fight or flight
norepinephrine
which neurotransmitter involves movement and pleasure
dopamine
which neurotransmitter regulates mood, sleep, and appeite
serotonin
which neurotransmitter slows the nervous system down after fight or flight and is also used the prepare the body for sleep
GABA
which neurotransmitter helps focus and complete tasks
glutamate
which neurotransmitter is your natural pain killer
endorphins
which nervous system contains all the neurons and nerves that aren’t in contained in the brain and spinal cord but that run through the body itself
