Somatosensory system

The somatosensory system is like your body's sensing system. It's all about how your body knows what's going on around it. Every part of your body is covered with nerve endings that send information to your brain about what's happening, like if something is hot or cold, bumping into something, or feeling pain. That way, your brain can help you know if you should move away from something, if something hurts, or if you should be careful.
