Episode notes
Nose Warms, Humidifies, And Can Be Shrunk
- The nose humidifies and warms inspired air using turbinates to increase surface area.
- Vasoconstrictors shrink nasal blood vessels to reduce bleeding and improve scope passage.
Memorize Pharyngeal Divisions
- Remember nasopharynx, oropharynx, and hypopharynx and that soft palate separates naso- and oropharynx.
- Learn both epiglottis and hyoid as separators since sources vary and exams might test either.
Cranial Nerves Drive Upper Airway Sensation
- Upper airway sensory innervation is cranial-nerve based with V1/V2 for the nose and CN IX for posterior tongue and tonsils.
- Vagus provides sensory innervation below the epiglottis.
