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

• External nares
