Supralaryngeal

Supralaryngeal refers to anatomical structures or processes located above the larynx, also known as the voice box. The larynx is situated in the neck, below the pharynx and anterior to the esophagus. Therefore, supralaryngeal structures are those found in the region of the throat superior to the vocal cords.

This region includes parts of the pharynx, such as the oropharynx and nasopharynx, as well as muscles, nerves, and blood vessels associated with swallowing, breathing, and speech production. The tongue, soft palate, and epiglottis are all considered supralaryngeal structures due to their position above or at the level of the larynx and their role in controlling airflow and food passage.

In the context of speech, the supralaryngeal vocal tract is the resonating cavity above the vocal folds. Its shape and size can be altered by the movement of articulators like the tongue, lips, and soft palate, which in turn modifies the sound produced by the larynx, creating different vowels and consonants. The term is also used in medicine, particularly in oncology, to describe tumors or surgical resections that involve structures above the larynx.
