Nervous System Control
Your nervous system is like your body's high-speed internet, providing fast, immediate communication between your brain and every part of your body. It's made up of the central nervous system (brain and spinal cord) and the peripheral nervous system (all other nerves).
Your brain has three key regions with different jobs. The cerebrum handles conscious thought, memory, emotions, and movement. The cerebellum controls balance and coordination - essential for sports and even just walking. The medulla manages unconscious actions like breathing and heart rate.
This system works 24/7, processing millions of signals every second. Whether you're solving maths problems (cerebrum), riding a bike (cerebellum), or sleeping peacefully (medulla), different brain regions are constantly at work.
Amazing Fact: Your brain uses about 20% of your body's total energy - that's why thinking hard can make you feel tired!
