CMAP is compound muscle action potential. The muscle is stimulated and an action potential is recorded. Muscle facilitation is the opposite of muscle inhibition, so I think it is kind of a nonspecific term that can refer to normal activity or hyperactivity.

I saw a couple of questions (Uworld/nbme) in which you were required to know the difference between this and Action potential and diseases which could affect it in different ways (MG/Lambert eaten/botulism). Anywhere I could read up on all of this or just stick to the Uworld explanations?
