What is the olfactory receptor?

olfactory receptor is a small contact point on certain nerve cells used for processing padorants. Odorants are chemical signatures that are mostly blended in substances and creatures. Tyto molekulární chemikálie jsou častěji označovány jako „vůně“.

Many biologists come from smell as one of the most important tools for survival of any body. In fact, they have almost all living things, from simple invertebrates to humans, at least a certain amount of olfactory receptors. For example, fish have approximately 100 varieties of these places, while people have about 10,000. Nearly 3% of the human genetic code is dedicated to the construction of the olfactory receptor. It allows people to recognize factors about everything from fitness and the health of a potential partner to identifying poisonous substances and edible food. It is closely associated with memory, in fact much more than any other Sense.

When a person uses a food substance that is rotten or causes to be sickIt is the smell in its memory bank. When Padorant enters his nose from this food or drink, olfactory receptors remind him of this occurrence and is unlikely to eat or drink this substance again. This principle also applies to poisonous or useful substances.

Try to imagine odorants like keys and every olfactory receptor as a lock. Any odor is associated with its corresponding receptors, which will allow one to identify the smell. One odorant often activates many receptors because they are more tuned to the properties of the substance than the substance itself.

This makes the sense of smell able to identify previously uncharacterized odorants. This is achieved when the olfactory receptor converts information from odorants to nerve pulses that B, which Bdéšť then processes and categorizes. Olfactory receptors are so versatile that they are able to identify an almost endless combination of odors.

Millions of olfactory receptors are connected to small groups in the back of the nasal cavity. This group for the formation of olfactory epithelium. The olfactory receptors are associated with an epithelium that is covered with a cilia of hair. These cilia collect inhaled odorant molecules and send them to olfactory receptors. The mucus, which lines our nose and cavity, also helps to capture these padorants, allowing them to process.
