somatosensory system
complex system of sensory neurons and pathways that responds to changes at the surface or inside the body
AI overview
The somatosensory system is a network of sensory nerves throughout your body that detects physical sensations like touch, temperature, and pain from both your skin and internal organs. It matters because it allows your brain to sense what's happening inside and around your body, which is essential for everything from feeling a handshake to knowing when you're injured.
