Ans: D
Non-striated muscles:
They are not under the control of our will and so are called involuntary muscles. The walls of the internal organs such as the blood vessels, gastric glands, intestinal villi and urinary bladder contain this type of smooth muscle. Movement of food in the alimentary canal or the contraction and relaxation of blood vessels are involuntary movements.
