muscle memory

[DLKeeper1]

I don't know too much either but from what I've read I think that it's the neural paths being memorized in your brain. In other words, the pattern of doing certain movements is memorized by your brain. This applies in several ways. Your body becomes as efficient as possible if you keep doing the same routine, in other words it will use as little energy/muscle fiber to do the same motion. It will also make the movement easier (hence "practice makes perfect"). This has to do with building myelin (an electric insulator) around the axons of the neurons.

I don't really know how muscle memory applies to your question. It may not apply at all, I'm not sure.
