Explain the process of action potential. Include synaptic transmission in your explanation. (I'll become your fan and give you a medal for the best answer)

Question

anonymous · Answer

Action Potential is the reversal of charges across the cell membrane of a neuron; also called a nerve impulse.

anonymous · Answer

cell has more potassium inside than outside which has more of sodium.this gives a net negative electric charge inside cell maintained by na/k/atpase pump.
whenan impulse arrives it causes opening of voltage gated na channels.....which cause inpouring of na into cell ....in direction of concentation gradient.
this causes deploarisation ...and action potential

now in nerves ends acion potential arrives and causes calcium influx which releases stored acetyl choline into post synaptic cleft.....
