Synapse Transmission

Question 1

Synapse

Answer 1

connection btw 2 neurons

Question 2

neurotransmitters

Answer 2

messengers that carry neural signals from one neuron to another

Question 3

presynaptic axon terminals

Answer 3

release neurotransmitters/ send info

Question 4

synaptic cleft

Answer 4

gap of the synapse that neurotransmitters have to cross

Question 5

synaptic vesicles

Answer 5

sacs containing neurotransmitters that are triggered to attach to the membrane/release contents by impulse

Question 6

receptor protein

Answer 6

trigger ion-specific channels to open

Question 7

postsynaptic neuron

Answer 7

receive neurotransmitters that trigger depolarization and cause an impulse

Question 8

Ways neurotransmitters can be removed

Answer 8

diffusion
glial cells remove them
re-uptake by the presynaptic neuron
enzymes break them down

Question 9

acetylcholine

Answer 9

neurotransmitter contracts muscles contribute to vasodilation/peristalsis/bladder capacity and pressure and contribute to memories
broken down by enzyme cholinesterase

Question 10

excitatory neurotransmitters

Answer 10

open sodium channels and cause depolarization

Question 11

inhibitory neurotransmitters

Answer 11

open potassium chloride channels to make it harder for depolarization
