<h3>What are neurons and what do neurons perform?</h3>
Neurons are the primary functional components of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly convey information over large distances. Although glia primarily support the neurons, they are nonetheless crucial for the proper operation of the nervous system.
<h3>What makes neurons so important?</h3>
Information is transported throughout the human body by neurons. They assist in coordinating all of the vital operations of life by using electrical and chemical signals.
<h3>What three types of neurons are there?</h3>
