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 ...

Smell is due to molecules of a particular substance that travel into your nose. These odor molecules contact a tissue called the olfactory epithelium (Fig. 1), which contains olfactory receptor cells ...

By delivering an appetite-regulating hormone directly to the olfactory epithelium, the hormone was able to reach its target. Only the secreted hormone molecules crossed into the brain. Engineered ...

in an individual’s olfactory epithelium. This process is mediated by differential rates of turnover (i.e., the rates of birth and survival) among the different neuron subtypes. The mechanisms by which ...

Ahh. Let's continue. On the roof of the nasal cavity is the olfactory epithelium, which contains nearly 40 million special receptors that are sensitive to odor molecules traveling through the air.

known as the olfactory epithelium. These cells connect directly to the brain. Each olfactory neuron expresses one odour receptor. When molecules from food or other substances are released ...
