Inferior concha Rating: 5,5/10 1873 reviews

The inferior concha, also known as the inferior nasal concha or the turbinate bone, is a small, curved bone located in the nasal cavity of the human skull. It is one of three conchae in the nasal cavity, with the other two being the middle and superior conchae. The inferior concha plays an important role in the respiratory system, helping to filter, humidify, and warm the air we breathe.

The inferior concha is a thin, scroll-shaped bone that is situated between the lateral wall of the nasal cavity and the upper part of the nasal septum. It is covered by a thin layer of mucous membrane, which helps to moisten and warm the air as it passes through the nasal cavity. The inferior concha is also lined with cilia, tiny hair-like structures that help to move mucus and trapped particles out of the nasal cavity and towards the pharynx.

In addition to its respiratory functions, the inferior concha also plays a role in the sense of smell. The olfactory neurons, which are responsible for detecting odors, are located in the mucous membrane lining the inferior concha. When we breathe in an odor, the olfactory neurons in the inferior concha send signals to the brain, allowing us to perceive the scent.

While the inferior concha is an important structure in the nasal cavity, it can sometimes cause problems if it becomes swollen or inflamed. This can lead to a condition known as inferior concha hypertrophy, which can cause difficulty breathing and a feeling of congestion in the nose. In some cases, surgery may be necessary to reduce the size of the inferior concha in order to alleviate these symptoms.

Overall, the inferior concha is a vital structure in the human respiratory system, helping to filter, humidify, and warm the air we breathe. It also plays a role in our sense of smell, allowing us to perceive the many different scents that we encounter in our daily lives.
