Cavities and Spaces of the Larynx Flashcards
Name 6 cavities and spaces of the larynx.
- Laryngeal vestibule
- Laryngeal ventricle
- Inferior Laryngeal ventricle (subglottal atrium)
- Valleculae
- Pyriform sinus
- Glottis
Label The Cavities and Spaces of the Larynx
A - Laryngeal Vestibule
B - Laryngeal Ventricle
C - Inferior Laryngeal Ventricle (sub glottal atrium)
D - Valleculae
E - Pyriform Sinus
F - Glottis
Location of the laryngeal vestibule
- Area in the larynx above ventricular folds
What is the aditus?
- The opening that leads to the laryngeal vestibule
Location of the laryngeal ventricle?
- Space between the vocal folds and ventricular folds
Location of the inferior laryngeal ventricle (subglottal atrium)
- Portion below the true vocal folds
- Extends through to the trachea
Location of the valleculae
- Area between the tongue root and epiglottis
An impaired swallow can cause food/liquid to pool in which two areas?
What can this lead to?
- Valleculae
- Pyriform sinus
- Increases risk for aspiration
Location of the pyriform sinus
- Between the lateral wall of thyroid cartilage and aryepiglottic folds
Label The Glottal Openings
- A. Glottis (opening between vocal folds)
- B. Anterior commissure: the anterior-most region of the glottis
- C. Posterior commissure: the posterior-most region of the glottis
When is the glottis is triangular shaped?
- During quiet respiration
This is a diagram she included in her slides. It looked important. Including it here just in case. Great idea! Thanks!
