Question

Which of the following is/are the features of cardiac muscles?

• A. Involuntary
• B. Do not get fatigued
• C. Striated
• D. All of the above

Answer 1

The correct option is D All of the above

Cardiac muscles are the muscles of the heart. Many cardiac muscle cells assemble in a branching pattern to form a cardiac muscle. Based on appearance, cardiac muscles are striated. They are involuntary in nature. Since the blood supply to cardiac muscle cells is rich in oxygen, they do not get fatigued. Also, the number of mitochondria in cardiac muscle cells is more which provides ample energy for these muscles to work tirelessly. So, the correct answer is option D.
