CNS controls the body using the brain and the spinal cord, while PNS connects the CNS to all body parts through nerves.

What is the difference between the CNS and PNS?

Question:

What is the difference between the CNS and PNS?

Answer:

The nervous system is divided into two main parts: Central and Peripheral.

Feature	CNS (Central Nervous System)	PNS (Peripheral Nervous System)
Components	Brain + Spinal cord	Nerves outside the CNS
Function	Processing and decision-making	Transmitting messages to/from CNS
