They are specialised neurons in direct communication with the olfactory lobe in the brain. They differ from other neurons in having exposed receptor sites in the nasal mucosa that bind to various odoriferous chemicals.
When a specific chemical binds to its appropriate receptor site, the neuron foires, releasing the chemical which may well trigger a lot more neurons. This way the brain can distinguish what smells are important.
The system is poorly developed in man, but the dog has 100,000 times more receptors than we have. That's why drug sniffing dogs can find your stash so easily...
Partial answer: they are found in the nose, they serve to smell and identify smells, and they play a significant role in the taste of food.

What is sensorys receptor for smell?
the receptor cells in the olfactory membrane.....
A fracture of the ethmoid bone could result in damage to which cranial nerve?
Olfactory nerve. Olfactory nerve fibers arise from olfactory receptor cells located in olfactory epithelium of nasal cavity and pass through cribriform plate of ethmoid bone to synapse in olfactory bulb.
Before an olfactory receptor can detect an odorant it has to?
bind to receptors in olfactory cilia.
Where are bipolar amacrine and ganglion cells located?
Retinal Cells, Olfactory epithelium Cells
Which of these activates an olfactory receptor and causes the transmission of information about a smell?
odorant
What is sensorys receptor for smell?
the receptor cells in the olfactory membrane.....
Where is the olfactory epithelium found?
The olfactory epithelium occupies an area of about 5 cm2 in the roof of the nasal cavity. The specialized receptor cells in the olfactory epithelium are surrounded by supporting cells, non-sensory epithelial cells. The olfactory receptor cells are bipolar neurons whose olfactory cilia extend outward from the epithelium.
How do people smell food?
A specialized smell receptor is situated In the roof of the nasal canal,called Olfactory mucosa. the olfactory epithelium is innervated by the olfactory(1st cranial)nerve and some branches of the 5th nerve.Olfactory epithelium contains three kinds of cells,namely olfactory receptor cells,supporting cells and basal cells.Olfactory receptor cells are sensory hair cells,sensitive to all kind of cells.Their axons terminally join the olfactory nerve. Supporting cells are mucus-secreting columnar cells. Basal cells are the stem cells from which new receptor cells are formed.Olfaction,just like taste,is a chemical sense. The molecules of the odorous substances reach the nasal canal along with the inspired air. Here, they dissolve in the mucus secretion and then attach to the receptor cells. This stimulates the receptor cells and they generate olfactory impulses. Olfactory nerves transmit these impulses to the olfactory center in the temporal lobe of the cerebrum(known as the olfactory cortex)
These cells provide physical support nurshment and electrical insulation for olfatory receptors cells?
These cells are called sustentacular cells or supporting cells. They surround and support the olfactory receptor cells in the olfactory epithelium. They provide physical support, nourishment, and electrical insulation to the olfactory receptor cells, helping to maintain their function.
What are the cells that which the receptor cells of the neurons of the nose which are spread across the nasal cavity?
Olfactory Cells
What are the olfactory membranes?
The olfactory membrane is a layer of cells on the roof of the nasal cavity also called theepithelium, . It is made up of three layers, the supporting cells, the olfactory receptor cells, and the basal cells. Supporting cells help produce mucus. Basal cells are the source of new receptors. and Olfactory receptor cells, these are actually neurons and are the site of transduction. Olfactory receptor cells are the only neurons in the nervous system that are regularly replaced, lasting about about 4 to 8 weeks.
What special cells allow you to smell food?
Olfactory receptor cells are the receptors for smell.
A fracture of the ethmoid bone could result in damage to which cranial nerve?
Olfactory nerve. Olfactory nerve fibers arise from olfactory receptor cells located in olfactory epithelium of nasal cavity and pass through cribriform plate of ethmoid bone to synapse in olfactory bulb.
A fracture of the ethmoid bone would result in damage to which cranial nerve?
Olfactory nerve. Olfactory nerve fibers arise from olfactory receptor cells located in olfactory epithelium of nasal cavity and pass through cribriform plate of ethmoid bone to synapse in olfactory bulb.
What is a nose receptor cell?
An olfactory receptor cell is a specialized cell of the mucosal lining of the nose . These specialized cells serve as the receptors for smell.
Are auditory receptor cells located in the anvil?
yes the auditory receptor cells are located in the anvil
What are the sensory receptors for eyes and nose?
The sensory receptors for the eyes are the optic nerve and the retina. The sensory receptor for the nose are the olfactory nerves.
