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.

Otorhinolaryngologists must have a basic understanding of the olfactory system and the pathophysiological mechanism related to the peripheral and central olfactory pathways to help patients when diagnosing and managing olfactory dysfunction.
Olfactory System – Introduction to Neuroscience
Olfaction is the ability to sense and perceive volatile chemicals that are suspended in the air. The typical human can distinguish up to 10,000 distinct odors, ranging from the sweet aroma of esters produced by apples and oranges, to the putrid smells of sulfurous compounds produced by skunks and rotten eggs.

2023年5月1日 · The olfactory system serves multiple functions in humans. Through direct connection with the limbic system and cerebral cortex, smells intertwine with experiencing emotions and memories. Olfaction also serves a role in shaping behaviors and communication between animals. [16]
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. Once detected by sensory organs, nerve signals are sent to the brain where the signals are processed.
