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 sensory receptor for smell is called the olfactory receptor. These receptors are located in the olfactory epithelium in the upper part of the nasal cavity and are responsible for detecting and transmitting odors to the brain for interpretation.
What cells provide for the sense of smell?
Olfactory receptor cells located in the nasal epithelium are responsible for detecting smells. When odor molecules bind to these receptor cells, they trigger a signal that is sent to the brain for interpretation.
Which cell detect the smell?
Olfactory receptor cells, located in the nose's olfactory epithelium, are responsible for detecting smells. These receptor cells bind to specific odor molecules and send signals to the brain to process and identify different scents.
What is the receptor of the human nose?
The sensory receptors for your nose is the semicircular canals and the cochlea
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.
In what cells does a smell impulse begin?
A smell impulse begins in olfactory receptor cells located in the olfactory epithelium in the nasal cavity. These receptor cells detect specific odorants and send signals to the brain via the olfactory nerve.
What is sensorys receptor for smell?
The sensory receptor for smell is called the olfactory receptor. These receptors are located in the olfactory epithelium in the upper part of the nasal cavity and are responsible for detecting and transmitting odors to the brain for interpretation.
What cells provide for the sense of smell?
Olfactory receptor cells located in the nasal epithelium are responsible for detecting smells. When odor molecules bind to these receptor cells, they trigger a signal that is sent to the brain for interpretation.
Which cell detect the smell?
Olfactory receptor cells, located in the nose's olfactory epithelium, are responsible for detecting smells. These receptor cells bind to specific odor molecules and send signals to the brain to process and identify different scents.
What are the cells that detect smell called?
chemoreceptor.
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.
What are Olfactory receptor cells are essential for our sense of?
Olfactory receptor cells are essential for our sense of smell, as they are specialized neurons located in the nasal cavity that detect airborne odor molecules. When these molecules bind to the receptors on the olfactory cells, they generate electrical signals that are transmitted to the olfactory bulb in the brain. This process allows us to perceive and identify different odors, playing a crucial role in flavor perception, memory, and even emotional responses. Overall, olfactory receptor cells are vital for our interaction with the environment through the sense of smell.
What are the nerve cells that react to gases?
Olfactory receptor neurons are nerve cells that react to gases, specifically in the context of the sense of smell. These neurons are located in the olfactory epithelium in the nasal cavity and are responsible for detecting various odors in the environment.
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)
Where are olfactory receptors located?
Olfactory receptors are located in the nasal cavity, specifically in the olfactory epithelium. This specialized tissue lines the upper part of the nasal cavity and contains millions of olfactory receptor cells that are responsible for detecting smells.
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
