  • The nervous system is made up of specialized cells which includes nerve cells (or neurons) and glial cells (or glia)
  • Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances
  • Glia are also essential to nervous system function, but they work mostly by supporting the neurons
