There are many parts to a neuron. The cell body is called the soma. Inside the cell body is where the nucleus is. On the edges of the soma, there are objects that look like tree branches from a truck those are called dendrites. The dendrites are known as neurotransmitters. They collect information and send it through the body of the neuron and down the axon, which is covered with a myelin sheath, to the terminal button. The information travels from the terminal buttons of one neuron across a space known as a synapse to the dendrites of another neuron.
The neurons can be in three stages one is known as resting potential which is when the neuron is inactive or resting. Another stage is the action potential which is when the neurons is actively firing the messages through the axon to pass the message on. The last one is the local potential which is the graded potential receptor.
Channels have gates that are closed at a resting state, sodium ions that are positively charged move inward. The sodium channels are the first int the depolarization phase. Then the potassium channels open , allowing the potassium to flow out, producing repolarizing phase. Together the depolarization and repolarization phase last about one millisecond in a normal neuron.

There are three major classes of neurons. Sensory neurons which have to do with touch, odor, taste, sound, and vision. The second is Interneuron. These are found within the spinal cord and brain. They are stimulated by signals reaching the from sensory neurons other interneurons or both. Interneurons are also called association neurons. And last but not least is motor neurons. They transmit impulses from the central nervous system to the muscles and glands which carry out the response.
