Carcinoma in situ of middle ear and respiratory system (D02)
Clinical Information
Epiglottis - A thin leaf-shaped cartilage that is covered with LARYNGEAL MUCOSA and situated posterior to the root of the tongue and HYOID BONE. During swallowing, the epiglottis folds back over the larynx inlet thus prevents foods from entering the airway.
Eustachian Tube - A narrow passageway that connects the upper part of the throat to the TYMPANIC CAVITY.
Glottis - The vocal apparatus of the larynx, situated in the middle section of the larynx. Glottis consists of the VOCAL FOLDS and an opening (rima glottidis) between the folds.
