Nervous System Overview
Your nervous system is like the body's internet - it's a complex network of billions of neurons that control and communicate everything happening in your body. This system handles awareness, movement, thinking, speech, and all five senses, making it the ultimate control center.
The system splits into two main parts. The Central Nervous System (CNS) includes your brain and spinal cord - think of it as the main processing center. Your brain controls most body functions while your spinal cord acts like a major highway carrying messages between your brain and the rest of your body.
The Peripheral Nervous System consists of all the nerves outside your brain and spinal cord. Its main job is sensing what's happening in your environment and sending motor commands to your muscles and organs. Together, these systems gather information, transmit it for processing, decide on responses, and send out commands - all happening faster than you can blink!
Remember This: Your nervous system does four things: gather info, transmit it, process it, and respond to it.
