Quick fact

Ligaments contain sensory nerve endings that detect stretch and tension, feeding your brain information about joint position without you even thinking about it—a sense called proprioception.

Why this is interesting

Ever twisted your ankle and felt a sharp pain? That's a ligament stretching or tearing—but normally these tough bands silently keep every bone in your body from slipping out of place.
