Rside A&P12 Synapse

Which statements are true for a synapse:

• communication point between neurons

• axon touches dendrite

• neurotransmitters used

• two way communication

Which synapse structure releases the neurotransmitter?

• presynaptic membrane

• postsynaptic membrane

• NT receptor

• synaptic gap

Which synapse structure is a part of the dendrite?

• presynaptic membrane

• postsynaptic membrane

• NT vesicle

• synaptic gap

Where are neurotransmitters found before release?

• presynaptic membrane

• postsynaptic membrane

• NT receptor

• NT vesicle

Where do neurotransmitters take effect?

• presynaptic membrane

• postsynaptic membrane

• NT receptor

• NT vesicle

Synaptic gap:

• A

• B

• C

• D

• E

NT receptor:

• A

• B

• C

• D

• E

Presynaptic membrane:

• A

• B

• C

What affect does the action potential have on the axon terminal bud?

• causes influx of Ca²⁺

• causes influx of K⁺

• causes NT to be produced

• causes NT receptor to active

Ca²⁺ enters the axon terminal bud, causing:

• NT to be produced

• NT vesicle to move away from the presynaptic membrane

• NT vesicle to fuse with the presynaptic membrane

• NT to be broken down & recycled
