Neurons are the fundamental unit of the nervous system.The neuron is a specialized and individual cell, which is also known as the nerve cell. A group of neurons forms a nerve.
Dendrites – A branch-like structure that functions by receiving messages from other neurons and allow the transmission of messages to the cell body.
Cell Body – Each neuron has a cell body with a nucleus, golgi apparatus,endoplasmic reticulum, mitochondria and other components.
Axon – Axon is a tube-like structure that functions by carrying an electrical impulse from the cell body to the axon terminals for passing the impulse to another neuron.
Synapse – This structure functions by permitting the entry of a neuron to move an electrical or chemical signal from one neuron to another neuron.
