Sense of smell - Wikipedia
The sense of smell, or olfaction, [nb 1] is the special sense through which smells (or odors) are perceived. [2] The sense of smell has many functions, including detecting desirable foods, hazards, and pheromones, and plays a role in taste.

2023年5月1日 — Olfaction is the chemical sensation of gaseous odorants colloquially referred to as the ability to smell. The olfactory nerve (cranial nerve one) in coordination with other neuroanatomical structures in the nasal passages, neurotransmitters, and the cerebral cortex is responsible for carrying out this intricate chemosensory process.
15.9H: Olfaction - The Sense of Smell - Biology LibreTexts
2022年5月15日 — Smell depends on sensory receptors that respond to airborne chemicals. In humans, these chemoreceptors are located in the olfactory epithelium — a patch of tissue about the size of a postage stamp located high in the nasal cavity.
Olfaction - an overview | ScienceDirect Topics
Olfaction refers to the sense of smell, a unique sensory modality that plays a crucial role in mating, survival, and shaping the quality of life in humans. It involves the detection of chemical signals in our environment through a complex neuroanatomical structure and signaling cascades.
36.3: Taste and Smell - Biology LibreTexts
Taste, also called gustation, and smell, also called olfaction, are the most interconnected senses in that both involve molecules of the stimulus entering the body and bonding to receptors.
Olfaction – Basic Human Physiology
Explain the process by which odorants activate olfactory receptors. Trace the path of olfaction from the olfactory receptors, to the initiation of an action potential in the olfactory nerves, through the olfactory bulb, the olfactory tract, and to the various parts of the brain.

The Olfactory System and Your Sense of Smell - ThoughtCo
2021年8月17日 — The olfactory system is responsible for our sense of smell. This sense, also known as olfaction, is one of our five main senses and involves the detection and identification of molecules in the air.
Olfactory system - Wikipedia
The olfactory system, or sense of smell, is the sensory system used for olfaction (i.e., smelling). Olfaction is one of the special senses directly associated with specific organs. Most mammals and reptiles have a main olfactory system and an accessory olfactory system .
