I understand that muscle cramps result typically from a shortage of 
calcium, potassium, or hydration, or from fatigue, but what 
specifically goes on in the muscle at the cellular/molecular level?  Does 
that vary depending on the cause?   None of the anatomy & physiology or 
exercise physiology books I can find (or internet sources) explain it.
