Synaptic transmittion

what is the process by which the synaptic vesicles release the neurotransmitters across the synaptic gap?
exocytosis
1 of 10
what produces the exitatory or inhibitory impulses?
the Receptor molecules - after being bound to certain neurotransmitters
2 of 10
what determines how long the effects of the neurotransmitters are?
the speed of re uptake
3 of 10
How are neurotransmitters turned off?
by enzymes produced in the body
4 of 10
If an exitatory neuro tranmitter binds to a receptor site what happnens?
It sends an electric charge through the cell membrane creating excitatiory post synaptic potential EPSP
5 of 10
what does IPSP stand for
inhibitory synaptic potential
6 of 10
can a neerve cell recive booth EPSPs and IPSPs at the same time?
yes
7 of 10
What is spatial summation?
large numbers of EPSPs generated across multiple synapses increasing the chance of exitatory sinaptc tansmittion
8 of 10
What is temporal summation?
the generation of large number EPSP's at one synapse by multiple action potential signalsif exitatory
9 of 10
What happens if exitatory synapses are more active what happens?
the cell fires at a higher rate
