Neurons are the fundamental unit of the nervous system specialized to transmit information to different parts of the body.A neuron varies in shape and size depending upon their function and location. All neurons have three different parts – dendrites, cell body and axon.Parts of NeuronFollowing are the different parts of a neuron:DendritesThese are branch-like structures that receive messages from other neurons and allow the transmission of messages to the cell body.Cell BodyEach neuron has a cell body with a nucleus, golgi body, endoplasmic reticulum, mitochondria and other components.AxonAxon is a tube-like structure that carries electrical impulse from the cell body to the axon terminals that passes the impulse to another neuron.SynapseIt is the chemical junction between the terminal of one neuron and dendrites of another neuron.
