Olfactory receptor - Wikipedia
WEBOlfactory receptors (ORs), also known as odorant receptors, are chemoreceptors expressed in the cell membranes of olfactory receptor neurons and are responsible for the detection of odorants (for example, compounds that have an odor) which give rise to the sense of smell.
Olfactory receptor | Anatomy, Function & Signaling Pathways
WEBOlfactory receptor, protein capable of binding odour molecules that plays a central role in the sense of smell (olfaction). These receptors are common to arthropods, terrestrial vertebrates, fish, and other animals. In terrestrial vertebrates, including humans, the receptors are located on.
