PPT-Cells of the Nervous System

Two Categories of Cells Glial Cells Neurons nerve cells Glial Cells Provide support nourishment maintain homeostasis and form myelin Neurons Neurons are specialized cells that help you gather information about your environment interpret the information and react to it.
