The distribution pattern of adrenergic nerve fibers in the nasal and sinusal mucosa of dogs was investigated by the use of the fluorescence microscopic method of Hillarp and Falk. In the proper layer of the nasal mucosa, sympathetic nerve fibers were found distributed mainly to blood vessels; thus, spindle shaped areas of brillant fluorescence were noted in the outer portion of the media of arteries; The fluorescence was also observed relatively abundant around the adventitia. The specific fluorescence of high brilliancy was seen at around and in arterial and venous walls also in arterial and venous plexuses. These findings indicate that sympathetic nerve fibers are distributed in the nasal mucosa in such a pattern as to permit to serve the purpose of regulating blood flow through this structure.
