epiglottis cartilage
(framework of larynx)
(4) - Answer -flexible leaf like structure
-attached inferiorly to thyroid angle
-adverts food around the larynx during swallowing
-behind hyoid bone & root of tongue
2 laryngeal joints - Answer cricoarytenoid and cricothyroid
-they are 2 cartilages
cricoarytenoid
(1/2 laryngeal joints) - Answer -saddle (diarthroidial) joint
-anterior & posterior ligaments bind& restrict motions of the aryntenoids
-rocking & sliding
--swinging
cricothyroid
(2/2 laryngeal joints) - Answer -pivot (darthroidial) joint
-allows for increased separation between thyroid & cricoid cartilages in anterior midline
4 most important cartilages - Answer 1. thyroid = hyaline cartilage
2. cricoid = hyaline cartilage
3. arytenoid = hyaline cartilage
4. epiglottis = elastic cartilage
superior to inferior cartilages - Answer 1. thyroid
2. cricoid
intrinsic origin & attachment is... - Answer all w/in the structure
extrinsic origin & attachment is... - Answer in the organ of interest & other part is on the
, outside of the larynx
the 3 laryngeal cavities - Answer 1. supraglottal (vestibule)
2. glottal
3. subglottal
where is each located at?
-supraglottal (vestibule)
-glottal
-subglottal
--glottis - Answer supraglottal (vestibule) = above vocal folds
glottal = between vocal folds
subglottal = below vocal fold
--glottis = space between vocal folds
supraglottal laryngeal cavities
-superior border is _____ _____
-what is that?
(the 3 laryngeal cavities) - Answer adits laryngis
-triangular opening bounded by epiglottis (anterior) aryepiglottic folds (lateral) &
arytenoid apex (posterior)
supraglottal laryngeal cavities
a. ____ _____ is a deep depression lateral to adits laryngis
b. _____ lies below adits laryngus
c. bounded inferiorly by _________________
d. ______ lies just below ventricular folds
(the 3 laryngeal cavities) - Answer a. pyriform sinus
b. vestibule
c. ventricular (false) vocal folds
d. ventricle
