What are the sinus cavities?

sinus cavities, also known as paranasal cavities, are in the bones of the face that are designed to serve a number of important functions. People and many other animals, including birds, have cavities. These cavities are only visible on X -rays and in fact the sinus cavities are very unique and used as fingerprints in the forensic tests. The term "sinus" is in fact Latin for "cavity", which makes "sinus cavities" a somewhat excess term, although many people do not know about it.

There are four sets of cavities in the skull. Between the eyes are the cavities of ethmoid sinus, while the sphenoid cavities are behind the eyes. In the upper jaw, under the eyes, maxillary cavities can be found and the frontal cavities are above the nose. Each cavity is lined with a snusic membrane and numerous cilia, small hair that moves, forcing the contents of the cavities to move through the cavity and drain their nose.

One of the key functions of the sinus tdut is to drain mucus. Mucus is used to capture harmfulsubstances that could otherwise penetrate the body and are generated by the body all the time. The cavities facilitate the collection and drain of mucus so that they cannot accumulate and cause the development of infection. This reduces the risk of body infection because bacteria and viruses are captured in mucus and can also capture potential allergens.

These cavities also filter and heat the air inhaled by the body and act to relieve the skull. If the sinus cavities were filled with bones, the skull would be extremely heavy and dense, which would make movement more difficult. The cavities also add voice resonance and help protect the skull if the face is impact.

cavities can develop problems. The most common problem arises when it is filled with mucus and are not able, leading to sinusitis in which sinus sinus inflammation occurs. The inability to drain can cause pain and leaves people a feeling of difficulty and fatigue. Chronic sinusitis can be very irritating and in someTerms of cases may be used by surgical technique to increase cavities and their drainage stores to reduce mucus and liquid accumulation. Cancer can also evolve in cavities, with the potential to metastasize to other areas of the body.
