Noradrenergic Fibers in the Larynx

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 15 p m 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.
