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.
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.
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 – 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.
From molecules to perception: 126 years at the forefront of
Olfaction is one of the most elusive of the human senses. It sustains life by enabling several critical functions, such as our ability to locate and select food, our choice of...

Authors from some of the most respected laboratories in the world explore various aspects of olfaction, including genetics, behavior, olfactory systems, odorant receptors, odor coding, and cortical activity.
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.
Olfaction: anatomy, physiology, and disease - PubMed
In this article, we review the anatomic pathways of olfaction, from peripheral nasal airflow leading to odorant detection, to epithelial recognition of these odorants and related signal transduction, and finally to central processing.
