Nerves are able to create, amplify and propogate electrical impulses that run along their axon. These nerve impulses are a form of action potential that is carried by ions. The nerve impulse is in effect an electrical difference between the inside and outside of the axon and is caused by ion movements across the membrane. Nerve impulses can occur from a number of sources including sensiry cells, action potentials from other connected nerves or spontaneous depolarisation of the nerve cell membrane. | Nerves are able to create, amplify and propogate electrical impulses that run along their axon.
