Can someone explain what action potential and resting membrane potentional?

Question

I have trouble understanding what they are.

Answer 1

The resting membrane potential means that in a normal neuron, the outside of the cell has a different voltage than the inside of the cell. When there is a stimulus, like touch, for example, channels on the cell's membrane open, to allow positively charged ions to flow into the cell. The accumulation of positive ions that are now inside the cell make the inside of the cell more positively charged than when "resting". The influx of ions propogates along the length of the cell and can cause the release of neurotransmitters at the end of the axon.

Answer 2

resting membrane potential is when there it no action potentioal. this means that the inside of the axon is less positive than the outside of the axon. this is becasue there are more na ions than there are k ions inside the axon. the voltage at rest is usually around +40mv. action potential is when all this is reveersed. the axoon becomes permiable to na ions and they rush in making the inside more positive till about +70mv.
