Noradrenergic nerve fibers contribute to the sympathetic control of blood flow and glandsecretion. Distribution of noradrenergic nerve fibers in and around canine vocal folds was investigated by means of the fluorescence method. In addition, the spatial relationship of noradrenergic nerve fibers to the blood vessels and glands was determined with the use of the peroxidase anti-peroxidase method. Noradrenergic nerve fibers were found around arteries and arterioles whose diameter was 15μm or greater. No noradrenergic fibers, however, were observed around capillaries and veins. In the laryngeal glands, noradrenergic nerve fibers were observed adjacent to the arteries which entered the glands and near the basement membrane of acinous cells. The results suggest that noradrenergic nerve fibers regulate the blood flow in the arteries and arterioles and gland secretion in the larynx.
