Question

When supra maximal stimulus is given then

• A. Muscle contraction is more than normal
• B. Muscle contraction is less than normal
• C. Muscle contraction is below average
• D. None of the above

Answer 1

The correct option is A Muscle contraction is more than normal

At the maximal stimulus, all motor units are recruited. All muscle cells in the whole muscle are contracting. Any stimulus above the maximal stimulus is called a supramaximal stimulus (voltage) and the tension will not increase beyond that elicited by a maximal stimulus. Thus, the correct answer is option A.
