12.2 The Central Nervous System | 12.2 The Central Nervous System | 12.2 The Central Nervous System |
- The central nervous system is made up of the spinal cord and the brain.
- The spinal cord transmits messages to and from the brain and coordinates reflex responses.
- The parts of the brain are specialized for particular functions.
- The cerebral cortex contains motor areas, sensory areas, and association areas that communicate with each other.
- The reticular formation contains fibers that arouse the brain when they are active and account for sleep when they are inactive.
| - What structures compose the central nervous system?
