Which of the following are ways in which a graded response is achieved in a muscle contraction?

Choose all answers that are correct.

Solution

Graded response of muscle fibre is the varying degree of muscular strenght required to complete a task. It is done by either changing the frequency of stimulus or by changing the strenght of stimulus, i.e by varying the intensity of the action potential and by varying the number of muscle cells/fibers that contract.
