Question

Muscles, which are immune to fatigue, are

• A. Striped muscles
• B. Cardiac muscles
• C. Jaw muscles
• D. Skeleton muscles

Answer 1

The correct option is B Cardiac muscles

The internal movements are performed by the involuntary muscles. The involuntary muscles function on their own and cannot be controlled willingly. The cardiac muscles are the involuntary muscles which are responsible for the pumping of the heart. The heart pumps and supplies the oxygenated blood to the different tissues in the body. The smooth muscles are responsible for carrying out peristalsis in the tube like structures of the alimentary canal.

Thus, the correct answer is option B.
