Olfactory Epithelium

Olfactory Epithelium A dime-sized patch of nerve endings situated in the retronasal passage that connects the nose to the mouth. As we inhale through the nose or mouth, this little patch captures airborne aromas and flavors as they pass by and transmits the information to the olfactory bulb, which can distinguish the presence of and identify nearly 10,000 unique aromas even at very low concentrations.
