What are characteristics of olfactory receptor cells?

Olfactory receptor neurons (ORNs) are bipolar neurons that are activated when airborne molecules in inspired air bind to olfactory receptors (ORs) expressed on their cilia. The ORs belong to a G-protein-coupled receptor superfamily. The ORNs are located high within the nasal vault in the olfactory epithelium.

What are the characteristics of olfaction?

On the basis of the apparent similarities of perceived odour quality or confusions in naming, it was concluded that there were six main odour qualities: fruity, flowery, resinous, spicy, foul, and burned. Electrical activity can be detected with fine insulated wires inserted into the olfactory bulb.

What is an olfactory receptor?

Olfactory 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.

What type of receptors are olfactory receptors?

Olfactory receptors (ORs) belong to the G-protein-coupled receptor family and play a critical role in recognizing thousands of odorant molecules in the olfactory sensory system.
