Question

The ability of muscle to shorten forcibly when adequately stimulated is known as ________

Answer 1

The ability of muscle to shorten forcibly when adequately stimulated is known as contractility.

Explanation:

• Contractility is defined as the ability of muscle cells to contract forcefully to bring about movement in body organs.
• The folding of arms are results of contractility of biceps and triceps.
• Contractility of cardiac muscle to regulate pumping of heart is again a result of contractility of myocardial muscle.

Answer 2

The ability of muscle to shorten forcibly when adequately stimulated is known as contractility

Explanation:

The ability of muscle to shorten forcibly when adequately stimulated is known as contractility. Contractility is a wonderful phenomenon adapted by the muscles. It is very important for a muscle to have this contractility.

While folding our arms the muscle gets adequately stimulated to pull your arms. The arm ex-tensor muscle needs to contract to fold the arms. Muscle contraction happens to facilitate the movement of the arms. In contractility the muscles have the ability to pull and not to push.
