ANAT 025 Lecture Notes - Lecture 20: Rima Glottidis, Lingual Tonsils, Adenoid
Document Summary
Tissue extends into lumen of nasal passage. This increases surface area to get more mucus to trap the material and more blood to move the material. Once hair cells have been stimulated to cause impulses, excess energy comes out into the auditory tube and out into the atmosphere. When you swallow, the larynx closes and the epiglottis seals off larynx so that what you swallow goes into the digestive system and not into your trachea. The larynx is made out of cartilage. Cartilage is rigid, and you need to make sure that it is rigid so it stays open during impact to your neck. Looking at larynx and one o"clock orientation. Vocal chords: vocal folds (like vocal ligaments) Deep sound: vocal chords are open wide. Tissue on lateral side of vocal chords: vestibule folds. Whenever a drop of water or particle hits the vocal fold, this initiates a choking reflex (your larynx didn"t close fast enough!)
