*‘olfaction’ is the sense of ‘smell’*
.
(this sense is mediated by ‘specialized sensory cells’ of the ‘nasal cavity’ of ‘vertebrates’, which can be considered analogous to ‘sensory cells’ of the ‘antennae of ‘invertebrates’)
(in humans, ‘olfaction’ occurs when ‘odorant molecules’ bind to specific ‘sites’ on the ‘olfactory receptors’)
(these ‘receptors’ are used to ‘detect’ the ‘presence’ of ‘smell’)
(they come together at the ‘glomerulus’, a structure which transmits signals to the “olfactory bulb” (a brain structure directly above the nasal cavity and below the frontal lobe))
(many vertebrates, including most mammals and reptiles, have two distinct olfactory systems—the main olfactory system, and the accessory olfactory system (used mainly to detect “pheromones”))
(for air-breathing animals, the main olfactory system detects volatile chemicals, and the accessory olfactory system detects fluid-phase chemicals)
(“olfaction”, along with “taste”, is a form of “chemoreception”)
(the chemicals themselves that activate the “olfactory system”, in general at very low concentrations, are called “odorants”)
(although taste and smell are separate sensory systems in land animals, water-dwelling organisms often have one chemical sense)
(volatile small molecule odorants, non-volatile proteins, and non-volatile hydrocarbons may all produce olfactory sensations)
.
(some animal species are able to smell ‘carbon di-oxide’ in minute concentrations)
