Nerve impulses are signals that are transmitted along nerve fibers of the body.
These electrical impulses create:
The axons contain voltage-gated ion channels that are either opened or closed by depolarization (which is the opening of ion channels leading to changes in membrane potential)
Depolarization further causes other channels to open and close thus spreading across the entire length of the axon and into another nerve cell (neuron).
Myelin sheaths act as buffers and through salt conduction help increase the speed of electrical impulses through the neurons. Not every nerve cell is insulated with a myelin sheath.
