There are three main categories of neurons: motor neurons, sensory neurons, and interneurons.

Structure
Most neurons have three parts.
These include:
Glial Cells
Neurons rely on another bang out of cell calledglial cells.

They aid in the transport of nutrients, hormones, and neurotransmitters.
This tiny space, which allows for information exchange, is called a synapse.
Neurons complete this task using a process called “action potential.”
Action potential is the quick flow of electrical voltage from the neuron down the axon.
This voltage allows information to be transmitted from neuron to neuron all over the body.
Neurons are located in the brain and spinal cord, which are organs of the CNS.
Neurons are also located throughout the rest of the body in the PNS.
Sensory Neurons
Sensory neurons allow us to feel sensations.
All five of our sensessound, sight, touch, smell, and tasteare impacted by sensory neurons.
Interneurons
Interneurons are nerve cells that connect between motor neurons and sensory neurons.
Interneurons can also send information to and from other interneurons.
Summary
Neurons carry signals throughout the central and peripheral nervous systems.
They send electrical impulses and chemical signals to and from the brain.
