Hmm, what exactly are you looking for? The mechanics behind muscle contraction?
Basically, every muscle is wired up, and nerves from the central nervous system carry impulses straight to the muscles... which is how we get a contraction. If there's a "break in the connection" anywhere along that path, you've got a major issue on your hands—you just can't trigger a contraction voluntarily anymore. That's when electrical stimulation comes into play, just to try and maintain some semblance of muscle tone...
Is that what you were after?
