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 is the life span of an olfactory receptor?
According to Mackay-Sim, A. and Kittel, P. W. (1991), On the Life Span of Olfactory Receptor Neurons. European Journal of Neuroscience, 3: 209-215. doi: 10.1111/j.1460-9568.1991.tb00081.x their results indicate that olfactory receptor neurons live for at least three times the commonly accepted life span of 30 days.
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.
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 molecule is activated from the binding of an odorant to transmembranous receptor molecules on olfactory hairs?
G-Protein
What is sensorys receptor for smell?
the receptor cells in the olfactory membrane.....
Before an olfactory receptor can detect an odorant it has to?
bind to receptors in olfactory cilia.
What is the receptor organ of the nose?
olfactory membrane
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)

What is the sensory receptors for smell?
The olfactory receptor is found in the nose.
Which of these activates an olfactory receptor and causes the transmission of information about a smell?
odorant
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.
Each olfactory cortical neuron receives input from one receptor at a time?
False
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.
