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)


Are olfactory receptor cells unipolar neurons?

They are bipolar.


Olfactory receptor cells are best described as?

neurons


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.


Describe the cellular composition and the location of the olfactory epithelium?

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 the cells that which the receptor cells of the neurons of the nose which are spread across the nasal cavity?

Olfactory Cells


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.

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 olfactory receptor cells chemoreceptors?

yes, they respond to chemicals trapped in the mucus of the nasal cavity


What is the sensory receptor for smell?

The olfactory receptor is found in the nose.


Process of smelling?

So, we just learned this in anatomy. You breathe in an odogen. The odogen binds with protein receptors in the olfcatory cilium. A potential travels on an axon the olfactory receptor cells synapsing in the olfactory bulb. Then the filaments of the olfactory nerve synapses with mitral cells causing impulses to flow from the olfactory bulbvia the olfactory tracts.


Where are the receptor cells located?

It depends on what the receptor cells are for. If they are for vision, they are located in the retina of the eye. If they are for hearing, they are located in the organ of Corti, and so on and so forth.

Where are the receptors of smell located at in the nasal passages?

How is odor detected?

Within the nasal cavity, odorant molecules interact with the cilia on odorant receptor cells. The binding of odorant molecules onto receptor proteins causes a net change in the membrane permeability of the receptor cells which then causes an action potential to be generated by the receptor cell. Unlike other senses, olfaction is not redirected by the Thalmus. It instead goes directly from the afferent receptor cells to the olfactory bulb. From the olfactory bulb, the action potential is sent directly to the cerebral cortex, specifically the limbic system (this is why there is a large emotional association with smell).
