Olfactory Triangle

The olfactory triangle (trigonum olfactorium) is an anatomical formation that is located in the upper part of the nasal cavity and is part of the olfactory analyzer. The olfactory analyzer is a part of the nervous system that is responsible for the perception of odors.

The olfactory triangle consists of three main parts: the olfactory lobe, the olfactory triangle, and the olfactory area. The olfactory lobe is located in the brain and is responsible for processing information received from the olfactory receptor. The olfactory triangle is located on the lateral wall of the nasal cavity and contains the olfactory bulbs and olfactory nerves. The olfactory areas are located in the upper part of the mucous membrane of the nasal cavity.

When a person inhales air, the olfactory receptors located in the olfactory triangle detect molecules of odorous substances. These molecules are then transmitted to the olfactory lobe of the brain, where they are processed. As a result of this processing, a person can identify the odor that was perceived.

In addition, the olfactory triangle plays an important role in regulating respiration and body temperature. For example, when air with a high concentration of carbon dioxide is inhaled, receptors in the olfactory triangle are activated that stimulate the respiratory center in the brain, resulting in an increase in respiratory rate and deeper breathing.
