Neurotransmitters
問題一覧
1
is the site of communication between a neuron and a target cell
synapse
2
refers to the neuron sending the signal
presynaptic cell
3
refers to the target cell receiving the cignal
postsynaptic cell
4
is a process whereby neurotransmitters get reabsorbed back into the presynaptic neuron they came from
reuptake
5
If a neurotransmitter is ________, it will increase the likelihood that the neuron will fire action potential.
ex: epinephrine and norepinephrine.
excitatory
6
If a neurotransmitter is _______, it makes the likelihood of the neuron firing action potential will be
decreased.
ex: GABA and endorphins.
inhibitory
7
> If a neurotransmitter is a
________, this means it can affect a largenumber of neurons at the same time, as well as being able to influence the effects of other neurotransmitters.
>do not directly activate the receptors of neurons but work together w/ neurotransmitters to enhance the excitatory or inhibitory responses of the receptors.
ex:serotonin and
dopamine.
modulatory/neuromodulators
8
>fight or flight
>produced in stressful situations. Increases heart rate and blood flow, leading to physical boost and heightened awareness.
adrenaline
9
>calming
>Calms firing neryes in the central nervous system.
>High levels improve focus, low levels cause anxiety.
>Also contributes to motor control and vision.
GABA
10
>affects attention and responding actions in the brain
>contracts blood vessels increasing blood flow
noradrenaline
11
> learning
> involved in thought, learning and memory.
> Activates muscle action in the body.
> Also associated with attention and awakening.
acetylcholine
12
> pleasure
> feelings of pleasure, also addiction, movement and motivation
> People repeat behaviors that lead to ______ release.
dopamine
13
> memory
> Most common neurotransmitter.
> Involved in learning and memory,
> regulates development and creation of
nerve contacts.
glutamate
14
> mood
> contributes to well-being and happiness. > Helps sleepcycle and digestive system regulation
> Affected by exercise and light exposure.
serotonin
15
> euphoria
> Released during exercise, excitement and sex producing well-being and euphoria, reducing pain
endorphins
16
> is commonly prescribed to treat
attention deficit hyperactivity disorder (ADHD).
> It stimulates the release of neurotransmitters, particularly dopamine and norepinephrine, in the
brain.
> This increased release enhances focus,
attention, and alertness by improving
communication between neurons in the areas of the brain responsible for these functions.
adderall
17
> SSRI
> used to treat depression. It works
by blocking the reuptake of serotonin, a
neurotransmitter associated with mood regulation. By preventing the reabsorption of serotonin, ______ increases the concentration of serotonin in the synaptic cleft, promoting improved mood and reducing symptoms of depression.
prozac
18
SSRI
Selective Serotonin Reuptake Inhibitor
19
> contains neurotransmitters
> located in the axon terminal
synaptic vesicle
20
> increase food intake
> storage of energy as fat
> reduce anxiety, stress
neuropeptide Y
