biopsychology: synaptic transmission Flashcards
1
Q
draw and label synaptic transmission
A
pre synaptic neuron:
- vesicle
- action potential
- neurotransmitters
post synaptic neuron:
- receptors
- synapse
2
Q
- what first triggers the neurone?
A
the action potential triggers vesicles containing neurotransmitters to move
3
Q
- what do the vesicles fuse with?
A
the membrane and release neurotransmitters into synapse
4
Q
- where do neurotransmitters diffuse and what do they bind to?
A
across the synapse and bind to receptor sites on post synapse
5
Q
- what happens once enough receptors have neurotransmitters bound to them?
A
the signal is then transferred
6
Q
- what is summation?
A
the net effect of the excitatory or inhibitory potentials
7
Q
what happens when there is more excitatory neurotransmitters or more inhibitory neurotransmitters?
A
more excitatory neurotransmitters leads to a positive charge and the messages are more likely to fire
more inhibitory neurotransmitters leads to a negative charge and messages are less likely to fire
