I've read that humans have some sort of a **kinesthetic model** of their body and muscles. This internal representation of the body is used to control and coordinate locomotion. I don't remember if feeling of pain is related to the same model.

I've checked the articles below in hopes of recalling what the correct term for the kinestetic model was, but was unable to find it. Sensory Homunculus concept seems close, but doesn't ring the bell. **Can someone suggest what the correct term for the internal representation used to coordinate motion is?**
