How is an Action Potential produced in a neurone?

It is all to do with the movement of ions in and out of the neurone cell, which changes the potential difference accross the cell's membrane. - In a neurone's resting state, the inside of membrane is more ne...

Explain the difference in the speed of conduction of an action potential along the length of a myelinated neurone and a non-myelinated neurone.

First, we need to explain how the action potential is conducted along the length of the axon. An action potential is transferred along an axon by the movement of Na + and K + ions into and out of the cell. T...
