A '''neuron''' or nerve cell is the functional cellular unit of the [[nervous system]], along with the [[neuroglial]] cell it makes up all [[nervous tissue]]. Neurons are cells that can propagate an [[electrical impulse]] across the cellular membrane. The cell is divided into three major parts the [[dendrites]], [[soma]] or cell body, and the [[axon]]. The archetypal neuron receives input at the tips of the dendrites, integrates that information at the cell body and outputs a signal impulse along the axon. However, there significant variation in cellular architecture and function across the animal kingdom.
