A neuron is a specialized cell, primarily involved in transmitting information through electrical and chemical signals. They are found in the brain, spinal cord and the peripheral nerves. A neuron is also known as the nerve cell.
The structure of a neuron varies with their shape and size and it mainly depends upon their functions and their location. Neurons are the structural and functional units of the nervous system. A group of neurons forms a nerve. Neurons are the structural and functional units of the nervous system. In humans, there are two types of neurons:
- Sensory Neurons
- Motor Neurons
The diagram or the structure of the Neuron is useful for both Class 11 and 12 board exams as it has been repetitively asked in the board examinations. It is also one among the few topics having the highest weightage of marks.

Diagram Of Neuron with Labels
Here is the description of human neuron along with the diagram of the neuron and their parts.
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.
