Which of the following actions is involved in developing tension in muscle fibres?

Question

Quizplus · Accepted Answer

Contraction of sarcomeres involves the sliding of actin filaments over myosin filaments, which results in the shortening and tightening of the entire muscle fibre. This process creates tension within the muscle. Lengthening of sarcomeres (B) would not create tension but rather result in muscle relaxation. Pushing of myosin by actin (C) and elongation of myosin fibres (D) are not accurate descriptions of the process of muscle contraction.
