Question

Quizplus · Accepted Answer

Twitch contractions are the brief, involuntary contractions of a muscle fiber that can be seen in an isolated muscle. However, they play a minimal role in normal muscle activity as they do not produce significant amounts of muscular force. Isometric contractions involve the maintenance of a constant muscle length without movement, while isotonic contractions involve movement with a constant amount of tension. "Tectonic" is not a recognized type of muscle contraction.
