If electrical resistance is high, current flow will be ___
The synaptic delay is due to
- 1) the time it takes for the neurotransmitter to be released from the synaptic cell
- 2)the time it takes a neurotransmitter to diffuse across the cleft
Which of the following ions are higher in concentration within the cytosol compared to extracellularly?
EPSPs ________ a postsynaptic cell.
a)prevent the subsequent release of neurotransmitters
b)Prevent the production of action potentials in
c)Increase the likelihood of subsequent release of neurotransmitters by
d) Increase the likelihood of an action potential being generated in
A _____ potential is decremental; that is the flow of charge decreases as the distance from the site of origin increases unlike the ____ potential which is regenerated in each section of the axon membrane.
Th period of time when only a strogner stimulus can produce another aciton potential in the membrane is known as the _____.
relative refractory period
If the sodium voltage gated channels become stuck in the inactivation phase, what effect would this have on the action potential?
After an initial action potential the cell would not generate any more APs. The cell would remain in its absolute refractory period
