1. Motor neurons
2. The brain stem
3. The cerebrum
4. The cerebellum

This part of the CNS stores your memories and coordinates interpretation.

1. The spinal cord
2. The brain stem
3. The cerebrum
4. The cerebellum

This part of the CNS coordinates automatic functions like breathing and your heart beat.
