Answer 1

Answer: (A)

Semi-spindle, involuntary

There are three types of muscles present in the human body. They are skeletal, smooth and cardiac muscles. Cardiac muscles are different from the skeletal muscles. The cardiac muscles are short when compared to the skeletal muscle cells. The shape of the cardiac muscles is referred to as semi-spindle. Skeletal muscle cells are cylindrical. Skeletal muscles are controlled by the somatic nervous system whereas, the cardiac muscles are involuntary in function.

So, the correct answer is option A.
