Question

What will happen to a muscle fibre when it is constantly acted upon by stimuli?

• A. The muscle stops contracting
• B. Tetanic contraction
• C. The duration of response decreases
• D. None of the above

Answer 1

The correct option is B Tetanic contraction

If the stimuli for contraction reach a muscle at a high rate, the muscle would have no time to relax; the contractions would overlap and the muscle as a result would continuously twitch or contract. This is called tetanic twitch or tetanic contraction.
