Separate senses with their own receptor organs

- 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.

Apr 1, 2012 · Just as sound is the perception of changes in air pressure and sight the perception of light, tastes and smells are the perception of chemicals in the air or in our food. Separate senses with their own receptor organs, taste and smell are nonetheless intimately entwined.

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...
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 (gustation) and smell (olfaction) are called chemical senses because both have sensory receptors that respond to molecules in the food we eat or in the air we breathe. There is a pronounced interaction between our chemical senses.
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).
Sep 23, 2024 · Sight, hearing, touch, taste, and smell are the five senses that enable us to understand our surroundings through different types of sensory input.
The sense of smell, or olfaction, [nb 1] is the special sense through which smells (or odors) are perceived. [2] The sense of smell has many functions, including detecting desirable foods, hazards, and pheromones, and plays a role in taste.
