Proprioception (from Latin proprius, meaning “one’s own” and perception) is the sense of the relative position of neighbouring parts of the body.

That’s a fancy word for your body’s sense of its own physicality — its “map” of itself. Proprioception is how you know where your various body parts are — and what they’re doing — even when you’re not looking at them. It’s why you can pass a baseball from one hand to another behind your back; it’s how you can climb stairs without looking down at your feet.
