Nervous System Introduction
Your nervous system works like your body's communication network, constantly sending and receiving messages to keep everything running smoothly. It's responsible for all your sensations, movements, thoughts and automatic functions like breathing.
The nervous system has two main divisions. The central nervous system (CNS) includes your brain and spinal cord, serving as the command centre. The peripheral nervous system (PNS) connects the CNS to the rest of your body.
Your brain is truly remarkable – it's the control centre that handles everything from complex thoughts and memories to emotions and voluntary movements. Think of it as your body's most sophisticated computer!
Fascinating fact: Your nervous system processes information faster than the world's most advanced computers, with signals travelling up to 120 metres per second through certain nerves!
