Nerve impulse action potential

The resting membrane potential refers to the non-excited state of the nerve cell at rest Action Potential. An action potential occurs when the nerve cell is in an excited state while conducting nerve impulses. Polarization. An action potential is the result of a very rapid rise and fall in voltage across a cellular membrane, with every action potential (impulse) similar in size. The response of a nerve or muscle cell to an action potential can vary according to how frequently and for what duration the action potentials are fired.

An action potential is the change in voltage across a cell membrane as a nerve impulse is transmitted. So basically as a nerve impulse is transmitted the voltage will change.and this change is called the action potential. Whereas nerve impulses are messages which are sent to the brain or muscles.

When a nerve impulse is generated, there is a change in the permeability of the cell membrane. The sodium ions flow inside and potassium ions flow outside, causing a reversal of charges. The cell is now depolarised. This depolarization results in an action potential which causes the nerve impulse to move along the length of the axon.
