How Your Sense of Smell Works Olfaction(also known as olfactics) which is the medical term defining your sense of smell. It is part of the chemic sensing system, or the chemo- sensory receptors. Sensory cells in the look, mouth and pharynx have a role in helping constitute smells and taste flavors. Microscopic molecules released by substances, such as food, make water these sensory cells. Once the cells detect the molecules they send messages to the understanding, where the smell is identified. How does the brain recognize, categorize and memorize the huge variety of odors? In 1991, Richard Axel and Linda tear published a paper on how the brain interprets smell. Axel and inject discovered that 3% of the human bodys ingredient total is coded for the olfactive receptor types. Every olfactive receptor cell has only one type of receptor. Each receptor type can detect a small human activity of related molecules and responds to some with greater intensity than differents. Essentially, it was discovered that receptors cells ar extremely specialized to particular odors. The researchers also found that the olfactory receptor type sends its electrical impulses to a particular micro-region of the olfactory medulla. The micro-region, or glomerulus, that received the information then passes it on to the other parts of the brain.

The brain then interprets the odorant patterns produced by activity in the different glomeruli as smell. There 2,000 glomeruli in the olfactory bulbâ€"twice as many micro-regions as receptor cellsâ€"allowing us to perceive a multitude of smells. Olfactory, or smell philia cells, are stimulated by odors such as the fragrance of a gardenia or the smell of bread baking. These nerve cells are found in small patches of tissue (the olfactory membranes) to the highest degree the size of a postage stamp that are regain in the pair of clefts just under the bridge of the nose high inside the nose. Most air breathed in normally flows through the nose but only a small part reaches the olfactory... If you want to get a abounding essay, order it on our website: Orderessay
