Smell is a person’s sense of: where is the olfactory organ

What is the sense of smell

The olfactory sense is the sense of man, which gives him the opportunity to experience different smells. It allows to perceive more than 10 thousand different scents that are capable of, and to improve appetite and to lighten the mood and allow time to recognize the danger. The importance of the nose as the chief organ of smell, should not be underestimated. But, unfortunately, we remember him only during his defeat infections, when severe congestion to allow us to enjoy your favorite flavors. Below we will examine what is the biological role of smell as it is to maintain and improve it.

What role in our lives played by the sense of smell

Smell, touch and other senses are kind of tools that allow us to obtain information from the outside and know the world around us. Without them life would not be as colorful and interesting, but broken from childhood the sense of smell, moreover, may seriously distort the General view of the world.

The sense of smell is particularly important for warning us of danger, to set the mood and influence on the other senses. For example, the smell of baking immediately increases appetite, sour scent of lemon triggers the revitalization of the salivary glands, and the sound of the surf soothes our nerves and adjusts on a complacent harmony.

In General, the recognition of aromas is one of the highest functions of our nervous system, the impulses trigger the work of other organs and systems of the body, which leads to the emergence of certain emotions.

Losing the ability to recognize smells, the person becomes irritable and angry, because it is equivalent to a loss of vision or hearing and, consequently, can lead to deep depression. Below we will understand how this system works feelings and what needs to be done to prevent its dysfunction.

How does our sense of smell

The nose is considered to be the main olfactory organ. One of its functions is a perception floating around us stimuli. It will not be possible without the presence and normal operation of bodies such as:

  • The mucous membrane of the nasal passages;
  • The olfactory bulb and the filament;
  • Cortex;
  • The olfactory nerves;
  • The receptor cells.

The location of the olfactory receptors located at the intersection of the upper nasal passage and the nasal septum from the back of the nasal region. It covers the olfactory epithelium, which covers an area of 4 sq. cm, These receptors ensure the transmission of all the received signals in the brain that are recognized in cortex.

The olfactory receptors are closely associated with branches of the trigeminal and olfactory nerves, namely:

  • With dendrites that they look like sticks, framed olfactory cilia;
  • With nerve, which in appearance is very similar to thread.

Axons are considered to be Central processes of nerve cells. They through the cells of the ethmoid bone, which is located in the nasal cavity and penetrate into the skull in order to join are on the basis of its olfactory bulb. It is a separate part of the brain.

Thus, the question of where is the olfactory organ a simple answer impossible.

Initially the function of a reception signal of an odor takes over the nose and the receptors, but the recognition of odours does our brain, or rather a separate area of the cortex, referred to as the visceral brain, where the olfactory analyzers, regulating food, emotional, defensive and any other innate human activity.

To its other functions include regulation of hemostasis, support of vegetation, and ensure the normal development of emotions, memory, and volitional behavior in children.

Because the nose is the olfactory organ of a person, means its functions include regulation of the pace of thinking, because all elements of its analyzer odor involved in behavioral responses to a particular event, and in the process of remembering, and to initiate and other activity coming from the cortex. During the formation of in the brain the sensation of smell in man quickens breathing and heartbeat, and increased blood pressure.

Normal sensitivity of the nose distinguish between thousands of shades of different smells, while the scent of the animal distinguishes them more than one hundred thousand. But at the same time, the severity of the smell depends on what the physiological shape of the person remains and what time of day is checked his analyzers. It is scientifically proven that a deep sense of smell people have upon waking when they are hungry.

But after a year the nose significantly loses its sensitivity because a job processing information includes other organs – vision, hearing, speech, etc.

According to the data of medical research, the human sense of smell is slowly but steadily decreasing throughout his life. Due to irreversible atrophy of their receptors.

Older people hear around them the smell is much worse than their grandchildren. However, this decrease is physiological, that is normal.

But sometimes the feeling is dramatically reduced regardless of age reasons, which are most often diseases that are localized where is the olfactory organ. Namely:

  • In the presence of acute and chronic inflammatory processes in the nasopharynx;
  • If you have seasonal allergies that affect many organs of the senses;
  • When polyps and other growths on the mucous membrane of the nasal passages;
  • For dental problems;
  • When taking certain medicines;
  • With vitamin deficiency;
  • When the intoxication of the organism;
  • After the acute course of viral hepatitis.

In addition, reduced functionality of receptors and some serious diseases, including those associated with disorders of the brain and CNS (Alzheimer’s, cerebral palsy, epilepsy, etc.).

Ways to improve sense of smell

Normal blood supply of the organs of smell allows you to extend the life of its receptors, are responsible for the safety of this man’s feelings.
