The 78 pages that link to Olfaction, each with the reason it gives.

• DiffusionRelated: Odor molecules must diffuse through air and nasal mucus to reach olfactory receptors.

• Lateral lineCompared with: Olfaction tracks chemical cues rather than the physical movement of water.

• CarnivoraRelated: Many carnivorans use scent to locate food, recognize individuals, and mark territory.

• FlavoringRelated: Many flavorings contribute aroma through molecules detected by the nose.

• Sensory ecologyRelated: Chemical cues can persist and travel through habitats where other signals fail.

• Scent markingRelated: Olfaction lets animals sample and interpret chemical information in marks.

• ChemoreceptionBroader topic: Olfaction detects chemicals that reach receptors in the nasal cavity.

• FlavorRelated: Olfaction supplies much of the fine-grained identity commonly attributed to food taste.

• Chemical ecologyRelated: Chemical interactions depend on organisms detecting compounds in their surroundings.

• UrsidaeRelated: Bears use an acute sense of smell to locate food and assess their surroundings.

• AppetiteRelated: Food odors can trigger appetite before food is eaten.

• PerfumeryRelated: Perfumery depends on how the human olfactory system detects and distinguishes odors.

• AromatherapyNarrower topic: Inhaled aromas act first through the olfactory system.

• Nasal cavityNarrower topic: The nasal cavity hosts the receptors that initiate this sense.

• ChemoreceptorNarrower topic: Olfaction is the chemoreceptor system specialized for volatile substances.

• ScavengerRelated: Vultures and other scavengers use airborne odors to find carcasses.

• Scent houndNarrower topic: Scent hounds depend on olfaction to detect and distinguish the odor traces left by game.

• TongueCompared with: Smell contributes strongly to flavor, unlike the tongue’s taste system.

• BarbelCompared with: Smell detects distant chemical cues, while barbels inspect nearby surfaces and food.

• IncenseRelated: Incense fragrance is perceived through olfaction.

• AnetholeNarrower topic: Anethole’s characteristic scent is perceived through olfactory receptors.

• CamphorRelated: Camphor’s vapor activates odor receptors and produces its characteristic scent.

• Food pairingRelated: Aroma contributes heavily to flavor and can reveal shared compounds between paired foods.

• FragranceNarrower topic: Fragrance works by releasing molecules that the olfactory system can detect.

• Odor thresholdNarrower topic: Odor thresholds quantify the lower limit of this sensory process.

• OkapiRelated: Scent helps solitary okapis recognize territory and reproductive signals.

• AntennaRelated: Many antennae detect odors through olfactory receptors concentrated in their sensilla.

• Wine aromaRelated: It turns volatile molecules above wine into perceived smell.

• Grizzly bearRelated: A powerful sense of smell helps grizzlies locate food across large landscapes.

• Olfaction in birdsNarrower topic: Avian olfaction is one branch of this broadly shared sensory system.

• WalleyeRelated: Chemical cues can help walleye locate prey and respond to their environment.

• AardvarkRelated: Aardvarks rely heavily on smell to locate insect nests while foraging.

• Caproic acidRelated: Its odor is perceived when caproic acid molecules activate olfactory receptors.

• StrepsirrhiniRelated: Many strepsirrhines rely strongly on scent marking and chemical communication.

• Asian water monitorRelated: Chemical sensing helps it locate food, including prey hidden from view.

• CarawayRelated: Caraway’s volatile molecules produce its recognizable smell through this sense.

• DeodorantNarrower topic: Deodorants change which odor molecules reach the nose or how their scent is perceived.

• LinaloolRelated: Linalool’s volatile molecules activate olfactory receptors and produce a floral impression.

• OilbirdRelated: Oilbirds use smell, alongside vision and memory, to locate fruiting trees.

• PungencyRelated: Volatile pungent compounds reach nasal receptors and contribute sharp odors.

• PythonidaeRelated: Chemical cues complement the tongue-based sensing pythons use when tracking prey.

• Sloth bearRelated: A strong sense of smell helps sloth bears locate insect nests and other foods.

• Sun bearRelated: A strong sense of smell helps sun bears locate dispersed foods.

• CorythosaurusRelated: The large nasal passages prompted hypotheses about smell, but crest size alone does not establish olfactory ability.

• DiacetylNarrower topic: Airborne diacetyl is perceived through this sensory system.

• DysgeusiaRelated: Smell strongly shapes flavor, so olfactory impairment can be mistaken for a taste disorder.

• EucalyptolRelated: Its vapor produces the characteristic scent associated with eucalyptus oil.

• Gila monsterRelated: Tongue-flicking and scent detection help locate prey and eggs.

• NostrilRelated: Air entering the nostrils carries odor molecules toward the olfactory region.

• OdorNarrower topic: Odor is a perceptual quality within this broader sensory process.
