Sympathetic innervation of the nasal mucosa of the pig.
Nasal disorders such as atrophic rhinitis in the pig are widespread and are of economic importance in livestock production. A better understanding of the basic physiology of the nasal mucosa could help in the study and treatment of nasal disorders. This paper presents a simple method which may prove useful in studies on the autonomic innervation of the nasal blood vessels. The results demonstrate the great sensitivity of the nasal blood vessels to sympathetic activity and indicate that there may be a vascular connection between the two nasal passages.
