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.
