What is the nervous system?

Your whole body is actually wired up like a high-speed data network! It all starts with your SENSORY ORGANS, like your eyes and skin, which act like scanners to pick up info from the world around you. These inputs are instantly turned into tiny ELECTRICAL pulses by NEURONS, which are special cells that work like lightning-fast message carriers. These pulses then travel through your NERVES, the long cables spread out through your arms and legs to keep every inch of you connected. All those signals zip toward your SPINAL CORD, the thick central highway that protects the data as it shoots up toward your head. Finally, the signal reaches your BRAIN, the main control center that PROCESSES everything and decides exactly how you should react. It's happenin' faster than you can blink! Tiny Concepts.
