Muscle twitches, also called fasciculations, usually only affect a single muscle. They're characterized by tiny contractions inside the muscle, caused by a nerve impulse. Muscle spasms, also called muscle cramps, affect multiple muscle tissues and are brought on by a chemical imbalance in the body.isorders of the nervous system can also cause muscles to twitch.
