How the resting potential is maintained table
The resting potential of an axon and how it is maintained
How an impulse is transmitted in one direction along the axon of a neurone
How the membrane potential changes during an action potential
During the refractory period, a section of the axon is unresponsive. This is very important as it ensures that ‘new’ action potentials are generated ahead (ie. further along the axon), rather than behind the original action potential. This makes the action potentials discrete events and means the impulse can only travel in one direction. This is essential for the successful and efficient transmission of nerve impulses along neurones.
