Which of the following statements is FALSE about muscles? a. toned muscles react to stimuli quickly and powerfully c. excessive use of muscles can cause hypertrophy b. atrophy of muscles can cause an increase in their size d. prolonged disuse of muscles can cause atrophy

The correct answer is option b. "atrophy of muscles can cause an increase in their size".

Explanation:

Muscle atrophy is defined by the partial or total loss of muscles mass that results from disabling circumstances. Muscle atrophy results in weakness, since the ability of the muscle to exert force is closely related to its size. Therefore, is false to state that muscle atrophy can cause an increase in its size. Actually, is the opposite, an atrophy in a muscle results in a decrease in its size.
