Comprehensive Study Guide Ch: 1-8
The Neuron - correct answer ✔responsible for sending information through
the nervous system
Dendrites - correct answer ✔fibers that project from cell body, receives
information from other neurons
Cell Body - correct answer ✔includes nucleus and other important things
keeping the neuron alive
Axon - correct answer ✔Transmits message through neuron
Axon Terminals - correct answer ✔where a message is sent on to the next
neuron
Communication that occurs within a neuron is ________ in nature - correct
answer ✔Electrical
Information that comes into the dendrites is either ________ or ________ -
correct answer ✔excitatory or inhibitory, generating an electrical impulse or
not
Myelin Sheathe - correct answer ✔To aid in the transmitting of information
some neurons are wrapped in a fatty like substance the ______
______(insulator), which serves as a conductor speeding up the process
, Communication between neurons is ___________ - correct answer
✔Chemical
The axon terminals contain sacs of ____________, which are naturally
occurring chemicals in the nervous system that specialize in transmitting
information between neurons - correct answer ✔Neurotransmitters
Synaptic Gap - correct answer ✔The tiny space between the axon terminal
of one neuron and the dendrite of an adjoining neuron
SSRI - correct answer ✔inhibits serotonin uptake to aid those with
depression
Acetylcholine (Ach) - correct answer ✔Enables muscle action, learning, and
memory (ACh- producing neurons deteriorate as Alzheimer's disease
progresses)
Dopamine - correct answer ✔influences movement, learning, attention, and
emotion (Oversupply linked to schizophrenia; undersupply linked to tremors
and decreased mobility in Parkinson's disease and ADHD)
Serotonin - correct answer ✔Affects mood, hunger, sleep, and arousal
(Undersupply linked to depression; some antidepressant drugs raise
_________ levels)
Norepinephrine - correct answer ✔helps control alertness, arousal, and
attention (Undersupply can depress mood and cause ADHD- like attention
problems)
