The Nervous System

Parts of the neuron

Signal or impulses,are electriacal signals are electrical impulse.
Impulses flash along individual nerve cell or neurons.
Each neuron have three main parts.A cell body dentrites and
an axon.Dentrites are a branching  nerve fiber that carry impulses

toward the cell body. An axon is a nerve fiber that carries impulses
away from the cell body.

Ehen an impulse reach the tip of an axon ,another nerve cell can`t
pick up directly.That`s beacuse there is a gap between neurons.
This gap is called a synapse and it is a only tiny fraction of an  inch wide.
