Sense of smell - Wikipedia
The sense of smell has many functions, including detecting desirable foods, hazards, and pheromones, and plays a role in taste. In humans, it occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system. [3]
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.
The importance of the olfactory sense in the human behavior and ...
Olfactory sense is, in terms of evolution, one of the oldest senses, allowing the organisms with receptors for the odorant to identify food, potential mating partners, dangers and enemies. For most living creatures and for mankind smell is one of the most important ways of interaction with the environment.
The Olfactory System and Your Sense of Smell - ThoughtCo
Aug 17, 2021 · 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. Once detected by sensory organs, nerve signals are sent to the brain where the signals are processed.

May 1, 2023 · 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.
Smell (Olfactory) Disorders—Anosmia, Phantosmia & Others - NIDCD
Your ability to smell comes from specialized sensory cells, called olfactory sensory neurons, which are found in a small patch of tissue high inside the nose. These cells connect directly to the brain. Each olfactory neuron has one odor receptor.
