A) skeletal muscle
B) cardiac muscle
C) smooth muscle
D) voluntary muscle
Correct Answer: B
Solution :
[b] Cardiac muscles show characteristics of both smooth and striated muscles. These muscles are striated, cylindrical, branched and involuntary in nature. Cardiac muscles contract and relax rapidly, rhythmically and tirelessly throughout a lifetime, from early embryonic stage until death. Voluntary muscles are under our control and act accordingly to our need, e.g. skeletal muscles. Smooth muscles also known as striated, visceral or involuntary muscles are found in walls of hollow tubular organs like alimentary canal, ducts of glands, urogenital ducts and blood vessels except heart. They show slow contractions, but remain contracted for a long period of time.
