Autonomic innervation of the nasal mucosa.

The nasal passages play a crucial role in the protection and functioning of the lower airways. Consequently the nerve supply of the nasal mucosa is extensive, which is related to an immediate and adequate reaction upon a variety of external and internal stimuli. A brief review of the present knowledge on nasal autonomic innervation and pharmacology will be given. There is special attention to more advanced methods, such as radioligand receptor binding techniques, which might augment our insight in the significance of the nervous system in nasal (patho)physiology. Furthermore data on the secretory activity of the nasal glands in the rat and its neural regulation will be accentuated.
