Question

Which one of the following statements describes the cardiac muscle?

• A. Striated and involuntary
• B. Non-striated and involuntary
• C. Non-striated and voluntary
• D. Striated and voluntary

Answer 1

The correct option is A Striated and involuntary

The arrangement of the muscle proteins in cardiac muscle is similar to skeletal muscle in that it has an alternate dark and light bands or striations. These muscles are capable of generating strong contractions to support the pumping of blood through the body. However, unlike the skeletal muscles, they are not in control of the individual hence involuntary.

Smooth muscles are non-striated and involuntary, whose functioning cannot be directly controlled. Whereas skeletal muscles are striated and voluntary.
