Cleanup date February 2011 The olfactorysystem is the sensory system used for olfaction , or the sense of smell. Most mammals and reptiles have two distinct parts to their olfactorysystem a main olfactorysystem and an accessoryolfactorysystem . The main olfactorysystem detects volatile, airborne substances, while the accessoryolfactorysystem senses fluid phase stimuli. Behavioral evidence indicates that most often, the stimuli detected by the accessoryolfactorysystem are pheromones . The olfactorysystem is often spoken of along with the gustatory system as the chemosensory senses because ... 150px thumb Vesalius Fabrica , 1543.

PMID 18066954 ref Once ligands odorant particles bind to specific receptors on the external surface of cilia, olfactory transduction is initiated. In mammals, olfactory receptors have been shown to signal via G protein. This is a similar type of signaling of other known G protein coupled receptors GPCR . The binding of an odorant particle on an olfactory receptor activates a particular G protein G olf , which then activates adenylate cyclase , leading to cAMP production. cAMP then binds and opens Cyclic nucleotide gated ion channel . This opening allows for an influx of both Na sup sup and Ca sup 2 sup ions into the cell, thus depolarizing it. The Ca sup 2 sup in turn activates chloride channels, causing efflux of Cl sup sup , which results in a further depolarization of the cell. ref name Kato & Touhara A.Kato & K.

Olfactory fatigue , also known as odor fatigue or olfactory adaptation , is the temporary, normal inability to distinguish a particular odor after a prolonged exposure to that airborne compound. ref Odors chapter, Fundamentals volume of the ASHRAE Handbook , ASHRAE, Inc., Atlanta, GA, 2005 ref For example, when entering a restaurant initially the odor of food is often perceived as being very strong, but after time the awareness of the odor normally fades to the point where the smell is not perceptible or is much weaker. After leaving the area of high odor, the sensitivity is restored with time. Perfume counters will often have containers of coffee beans which tend to reset olfaction . Anosmia is the permanent loss of the sense of smell, and is different from olfactory fatigue.
