Question

Cardiac muscle is made of branched fibres that are

• A. Nonstriated and under voluntary control
• B. Striated and not under voluntary control
• C. Nonstriated and not under voluntary control
• D. Striated and under voluntary control

Answer 1

The correct option is B Striated and not under voluntary control

The involuntary muscles function on their own and cannot be controlled willingly. The cardiac muscles are the striated, involuntary muscles which are responsible for the pumping of the heart. These muscles are composed of branch muscle fibres. The heart muscle fibres relax and contract to pump and supply the oxygenated blood to the different tissues in the body.

Thus, the correct answer is option B.
