Neurotransmitters Flashcards
the first neurotransmitter discovered
acetylcholine
responsible for muscle contractions
ACh
This neurotransmitter STIMULATES skeletal muscles to contract yet SLOWS contractions in the heart; hence, this neurotransmitters is both excitatory and inhibitory.
ACh
if a neurotransmitter stimulates a response it is considered to be
excitatory
if a neurotransmitter can block a response it is considered to be
inhibitory
name the neurotransmitters that are both excitatory and inhibitory
ACh, Dopamine and Seratonin
what do ACh and Norepinephrine have in common?
they play a role in our arousal
what does “arousal” mean?
the state of being physiologically alert, awake, and attentive.
what do ACh and Glutamate have in common?
both are involved with memory
works primarily in muscles, helping our bodies translating our intention to move into actions
ACh
most abundant neurotransmitter and often considered the most important one too
glutamate
What do GABA and glutamate have in common?
both have the title “major.” GABA the major inhibitory neurotransmitter and glutamate the major excitatory neurotransmitter.
Which two neurotransmitters would be involved with diseases that involve memory loss, such as Alzheimer’s?
glutamate and ACh
newly linked with learning as well, this is the major inhibitory neurotransmitter; glutamate is its excitatory correlate
GABA
what does GABA stand for?
gama-aminobutyric acid
