Which of the following statements regarding skeletal-muscle contraction is true?

Question

Quizplus · Accepted Answer

During every muscle contraction, tension is developed in the muscle. This tension may or may not be enough to overcome the load on the muscle, resulting in either an isotonic or isometric contraction. However, muscle fibers do not necessarily change length during every contraction, as seen in isometric contractions where the muscle stays the same length while tension is developed. Additionally, a lengthening (eccentric) contraction occurs when the load on the muscle exceeds the tension developed by the muscle, resulting in the muscle elongating while still under tension.
