| the synapses send messages to the neurons. |
| the nerve cells become covered with smooth sheaths of fattyproteins that protect, insulate, and nourish them. |
| the neurons are spread throughout the brain to create itsstructure. 4- One of the primary functions of myelin is to: | provide an electrical conductor in the synapse. |
