Synapse Flashcards
1
Q
vesicles
A
contains neurotransmitters
2
Q
neurotransmitters
A
chemicals released from vesciles sending messages across synaptic cleft
3
Q
synaptic cleft
A
gap between 2 neurons
4
Q
what does the synapse consist of
A
presynaptic neuron:
- vesciles
- axon
- neurotransmitters
- synaptic cleft
post synaptic neuron
- dendrite
- receptors
5
Q
6 step process of synaptic transmission
A
- electrical impulse down axon to terminal button at presynaptic. triggers vesciles mvoe to end of terminal button
- release neurotransmitters into synaptic cleft
- neurotransmitters diffuse across synptic cleft to post synaptic
- neurotransmitter attaches to next neuron at post synaptic receptor sites
- chemical message turned back into eletrical to travel down postsynaptic
- neurotransmitters left in synaptic cleft broken down by enzymes + reabsorbed by presynaptic neuron for reuptake process
