Nodes of Ranvier

Gaps in the myelin sheath of nerve fibers that facilitate the rapid conduction of electrical impulses along the neuron.

Myelinated Neuron

A nerve cell that features a myelin sheath around its axon, enhancing the speed of electrical transmission of signals.

Action Potential

A short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, allowing neurons to transmit signals.

Depolarization

Depolarization is a process in nerve cells where the cell membrane's normal negative charge is reduced, allowing an action potential to occur and leading to the propagation of nerve signals.
