This is when the larynx begins its descent in the neck.
What is 18-24 mo?
100
The 3 paired and 3 unpaired cartilages of the larynx
What are the epiglottis, thyroid, cricoid, arytenoid, corniculate and cuneiform cartilages?
100
The folds that make up the lateral borders of the laryngeal inlet
What are the aryepiglottic folds?
100
This muscle is innervated by the external branch of the superior laryngeal nerve
What is the cricothyroid muscle
100
First otolaryngologist to use stroboscopy in north america.
Who is Dr. Morrison?
200
This is when the larynx reaches its final position.
What is 6 yrs?
200
Where the cricothyroid joint is located
What is postero infero laterally on the cricoid. (Pointing or drawing is fine)?
200
The potential space that extends superiorly and laterally from the vestibule and contains glands that secretes mucous
What is the saccule?
200
This muscle is the only abductor of the vocal cords
What is the Posterior Cricoarytenoid (PCA)
200
These are the "intrinsic" muscles of the larynx
What are the cricothyroid, the thyroarytenoid, the PCA, the LCA, and the interarytenoids.
300
The commonest age for foreign-body aspiration and why.
What is 18-24 months, because toddlers are able to get around and put things in their mouth?
300
These structures attach the epiglottis anteriorly and inferiorly
What are the hyoepiglottic ligament and the thyroepiglottic ligament?
300
The name of the free lower margin of the quadrangular membrane.
What is the vestibular ligament?
300
This muscle causes cord adduction by internally rotating the arytenoid at the muscular process.
What is the lateral cricoarytenoid
300
This is Dr. Morzaria's fellowship director at Stanford.
Who is Ed Damrose?
400
This is how you size an endotracheal tube in a child
What is age/4+4 or baby's little finger?
400
What are the most lateral, anterior and superior of the paired laryngeal cartilages?
What are the cuneiforms?
400
The names for the spaces between the true cords and spaces between the false cords
What is the rimma glottidis and the rimma vestibuli?
400
These are all the muscles attaching to the cricoid cartilage and the nerves that innervate them.
What are the cricothyroid (external branch of superior laryngeal) PCA, and LCA (RLN)?
400
These are the laryngeal elevator muscles
What are the stylohyoid, geniohyoid, and mylohyoid?
500
Four major differences between an infant and an adult larynx
What are: Infant size is 1/3 adult Positioned high in the neck (cricoid at C4 vs. C6) Epiglottis meets soft palate to enable breathing & suckling VC length (7-8mm vs 14-23mm) Cricoid diameter smaller than glottis (subglottis narrowest) Laryngeal cartilages are soft & collapse easy
500
This is the best drawing of the laryngeal framework (hyoid and 6 cartilages) from a posterior superior view
What is this!!!
500
The vocal ligament is a thickening of the free upper border of which structure?
What is the conus elasticus (or lateral cricothyroid ligament)?
500
These are the three muscles that attach to the thyroid oblique line
What are the thyrohyoid, inferior constrictor, and sternothyroid?
500
The five layers of the true cord and the related description of the theory of the mucosal wave.
What are the epithelium, the superficial, intermediate, and deep layers of the lamina propria, and the vocalis muscle? The cover-body theory - where the "cover" (the epithelium), moves easily over the stiffer "body" (the vocal ligament and vocalis), enabling a mucosal wave.
