Correct answer: C. Striated and involuntary
- A. Smooth and involuntary
- B. Smooth and voluntary
- C. Striated and involuntary
- D. Striated and voluntary
Explanation
The myocardium of the heart is both striated and involuntary.Striated means that the muscle fibers have a striped appearance when viewed under a microscope. This is due to the arrangement of the thick and thin filaments that make up the contractile apparatus of the muscle. Involuntary means that the muscle is not under conscious control. The contraction of the myocardium is controlled by the autonomic nervous system. The myocardium is the muscle tissue that makes up the walls of the heart. It is responsible for pumping blood throughout the body. The myocardium is striated and involuntary, which allows it to contract and relax rhythmically and automatically to pump blood.
