Smooth muscle
Smooth muscle is also found forming a thin layer in connective tissue near the luminal surface of hollow organs, such as those in the digestive or respiratory systems. In this field, the fascicles are cut in cross section. Also visible are two mast cells as well as numerous small blood vessels. 1000x
