Describe the process of action potential
Homework Answers
It occurs when the neuron sends the signal into the axon away from the cell body. There are 4 steps in action potential. They are
Maintenance of resting potential
Depolarization
Repolarization
Really establishment of resting potential.
I'm the first step sodium and potassium channels are closed. During depolarization sodium channels are open due to stimulus. During depolarization sodium channels get closed and potassium channels are open. Again the sodium and potassium channels are closed which leads to the establishment of resting potential.

Describe the events of an action potential is conducted down the membrane of an axon and how it is transmitted to another cell across a synapse causing an IPSP or an EPSP.
