About the Central Nervous System
- The central nervous system is also referred to as the CNS.
- The CNS has relay neurons which pass an impulse from the sensory neurons to the motor neurons.
- Impulses are sent via the nerves to the CNS where they are processed and a impulse is then sent back down the nerves to an effectors such as a muscle or gland.
