6. MODELS Upper Respiratory models: External nares Lingual frenulum Nasopharynx Oropharynx Laryngopharynx Uvula Epiglottis (“leaf-like” flap that covers the glottis) Glottis (this is a hole, so the question has to be something like “Name this opening”) Uvula Thyroid gland Palatine tonsil (tonsils are members of the immune system) Pharyngeal tonsil
