nasál

Nasál refers to anything related to the nose. In anatomy, it describes structures associated with the nasal cavity, such as the nasal bones, nasal septum, or nasal conchae. The nasal cavity itself is a space within the skull that is lined with mucous membranes and serves as the primary passageway for air entering and leaving the respiratory system. It plays a crucial role in olfaction, or the sense of smell, as olfactory receptors are located within the nasal cavity.

The term "nasál" is also used in phonetics and phonology to describe sounds produced with air passing through the nose. These are known as nasal consonants. Examples in English include the sounds represented by the letters 'm', 'n', and 'ng' (as in "sing"). In these sounds, the soft palate is lowered, allowing air to escape through the nasal cavity as well as the mouth. Many languages have nasal consonants, and their precise articulation can vary.

Furthermore, the word "nasál" can be used in medical contexts to refer to conditions or treatments involving the nose. For instance, nasal polyps are growths within the nasal cavity, and nasal sprays are medications delivered directly into the nose. The nasal passages are also susceptible to infections like sinusitis.
