“…On the basis of his findings, KAYSER [22] established that the nasal passages are subject to continual rhythmic changes in nasal resistance. The reciprocal spontaneous changes in unilateral nasal airway resistance, which constitute a nasal cycle, have been well documented by subsequent investigators [1][2][3][23][24][25][26][27][28][29]. The term "nasal cycle" is perhaps misleading as the spontaneous reciprocal changes in nasal REVIEW airway resistance have only rarely been shown to exhibit any regular pattern [25], and there is little support for a regular cycle [26,28,30].…”

“…The spontaneous reciprocal changes in nasal airway resistance, which constitute the nasal cycle, have been reported to be abolished after section of the cervical sympathetic nerve or local anaesthesia of the stellate ganglion [32,47,48]. In 1953, STOKSTED [3] speculated that oscillations in sympathetic tone regulated the nasal cycle and that there was a nasal control centre in the hypothalamus. Experiments on anaesthetized cats have demonstrated that pronounced nasal vasoconstriction can be induced on electrical stimulation of localized areas of the hypothalamus [49].…”

“…This asymmetry of nasal airflow is not fixed, as the dominant airflow alternates from one nasal passage to the other over a period of several hours [1][2][3]. The asymmetry in nasal airflow is exaggerated with nasal infection and one nasal passage may become completely obstructed whilst the other remains patent [4,5].…”

This review describes the phenomenon of the nasal cycle, which consists of periodic congestion and decongestion of the nasal venous sinusoids.The hypothesis is put forward that the nasal venous sinusoids participate in respiratory defence by generation of plasma exudate. This hypothesis is based on recent studies, which have shown that the nasal venous sinusoids have a fenestrated endothelium and that the nasal cycle is increased during periods of nasal infection; and also on a series of older observations in the literature, which link the generation of nasal fluid to the decongestion of nasal venous sinusoids.It is proposed that the periodic congestion and decongestion of nasal venous sinusoids may provide a pump mechanism for the generation of plasma exudate, and that this mechanism is an important component of respiratory defence.

“…There is a cyclic variation in the flow resistance of each nasal passage (6,7) which is due to the regular constriction and dilation of the mucosal venous cavernous tissue (8) and is thought to hypothalamically regulated (9) via the Vidian nerve (10). At the peak of the cycle, one nasal cavity has low flow resistance and the mucosa is moist while the other has high flow resistance and dry nasal mucosa (11).…”

The anatomy, physiology and function of the olfactory system are reviewed, as are the normal effects of olfactory stimulation. It is speculated that olfaction may have important but unobtrusive effects on human behavior.The sense of smell has been neglected in comparison to other senses. Among the reasons for this are (a) inaccessibility of anatomical structures, (b) limited theoretical knowledge about the nature of the physical stimulus, (c) difficulty with generating and presenting stimuli and (d) the belief that the olfactory sense is not important to man. Some of these reasons remain problems, but techniques for dealing with them are being devised (1). No recent major advance in olfactory stimulus theory has occurred. The belief about the unimportance of olfaction has been questioned recently and is discussed in this paper.The major reason for reviewing olfaction in a toxicological/environmental context is that this neural tissue is directly exposed to air pollutants. Since these olfactory receptors appear to function by retaining molecules on their surface, airborne pollutants and toxic substances have a high potential for producing olfactory damage. The olfactory system is perhaps the most vulnerable neural tissue in terms of airborne pollutants, since the receptors are: directly exposed and are also exposed via the circulatory system to bloodborne toxicants.This review describes the anatomy and physiology of the olfactory system and also discusses the behavioral implications of this sense.
