"The brain and the nervous system are composed of two types of cells—neurons and glial cells. Neurons are responsible for information transmission throughout the nervous system. Glial cells constitute the support system for the neurons. For example, glial cells take away the waste products of neurons, keep the neurons’ chemical environment stable, and insulate them, allowing neurons to do their work more efficiently."
