What are the two types of cells of the neuvous system?
What is the function of neurons?
Transmit nerve impulses.
What are the functions of neuroglial cells?
hold neurons together by filling spaces, supporting neurons, and serving as a framework
regulate the environment of the neurons
When does the ability for neurons to divide stop?
About six months after birth.
