- Taste and smell are separate senses with their own receptor organs, yet they are intimately entwined. Tastants, chemicals in foods, are detected by taste buds, which consist of special sensory cells. When stimulated, these cells send signals to specific areas of the brain, which make us conscious of the perception of taste.

Our ability to taste depends on the molecules set free when we chew or drink. These molecules are detected by gustatory cells in taste buds on the tongue and along the roof and back of the mouth. Each taste bud has sensory cells that respond to one of at least five basic taste qualities: sweet, sour, salty, bitter, and umami. All tastes are detecte...
Like taste, the sense of smell depends on detecting molecules. Odors are small molecules that can become airborne. They enter the nose on air currents and bind to specialized cells. These olfactory neurons reside on a small patch of mucus membrane high inside the nasal cavity. The tips of olfactory cells are equipped with several hair-like structur...
We lose some of our sensitivity to taste and smell as we age. The cells that process tastes and smells are exposed to the outside environment. Usually, since these cells are exposed and therefore vulnerable to damage, taste receptor cells regularly regenerate. However, as we age, damaged receptors and sensory neurons might not be replaced by new on...
You may notice the relationship between taste and smell when a cold stuffs up your nose and everything tastes bland. It seems like taste no longer works. The real problem is that during a cold, you’re detecting only taste, rather than taste and smell combined. Taste and smell information appear to converge in several central brain regions. There ar...
Taste, smell and flavour: How it all works. We explain why we taste things the way we do, and what ‘flavour’ really means. The terms taste and flavour are often confused. ‘Taste’ refers specifically to the five basic tastes (tastants) that we perceive in our mouth. Taste is one part of flavour.

Jan 24, 2023 · What we refer to as “taste” is basically a bundle of different sensations. It is not only the taste perceived by the tongue. The smell, texture and temperature of food play a role too. The “coloring” of a taste happens through the nose. The flavor of a food can only be determined when taste is combined with smell.

Taste and smell are closely related—they combine to produce our perception of flavor, and they rely on receptors (neurons) that actually come into contact with the environment outside our body. The rest of our sensory neurons are protected from the world by a layer of skin or some other tissue.
Jul 20, 2021 · Here’s what is known. Smell can impact your perception of flavor in one of two ways: as a constitutive part of that flavor, or as a modulatory force. In the former case, a smell is part of the flavor itself. And in the latter, a smell alters or adjusts your perception of a taste.
Sep 20, 2023 · The sense of smell plays a vital role in finding food, discriminating it from toxic substances, and appreciating its flavor (smell is a key component of what we commonly call “taste”-see below).
