Answer:
Linings of hollow organs
Explanation:
Smooth muscle cells are usually found in the lining of hollow organs such as all arteries and veins, wall of stomach, uterus, urinary bladder, digestive system etc. The cells of these linings are spindle shaped and consist of a nucleus at the center which lacks striations.
They work as a housekeeper and are under involuntary control except the heart. They lack striation because of irregular arraying of actin and myosin filament along the length of the cell.
