If a stimulus, several times greater than the threshold stimulus is provided to a muscle fibre, it will
Options
(a) Contract with a larger force
(b) Contract with a smaller force
(c) Contract with a same force
(d) Undergoes tetany
Correct Answer:
Contract with a same force
Explanation:
A muscle fibre would contract only when it receives stimulation of certain intensity called threshould stimulus. Response of a muscle fibre to a stimulus is not proportionate to its intensity. It is absent when the intensity is subliminal. Muscle fibre contracts to the maximum whether the stimulus has threshould value or supraliminal value.
