UNIT 4: Membranes Flashcards
extrinsic membranes of the larynx
connect laryngeal cartilages w adjacent structures for external support
intrinsic membranes of the larynx
connect laryngeal structures w each other for internal support
what covers the membranes of the larynx
mucous - most superficial layer
the thyrohyoid membrane is
a fibroelastic sheet
thyrohyoid membrane connects to _____ of the ____ to _____ of _____
inferior border of the hyoid bone to superior border of thyroid cartilage
there is an opening on the thyrohyoid membrane on each side for the
super laryngeal nerve iSLN of vagus
thyrohyoid membrane has 3 ligaments
1 medial
2 lateral
3 extrinsic membranes of the larynx
thryohyoid membrane
hyoepiglottic ligament
cricotracheal membrane
hyoepiglottic ligament is a ______ ligament connecting the corpus of the ____ and anterior surface of the _____
midline
hyoid
epiglottis
the hyoepiglottic ligament allows for
epiglottic deflection when relaxed
cricotracheal membrane connects the
lower border of cricoid w upper border of 1st tracheal ring
2 intrinsic membranes of the larynx
quadrangular
conus elasticus
the quadrangular membrane connects the _______ of the ____ to the apex and medial surface of _____
lateral margins of epiglottis
medial surface of arytenoids
quadrangular membrane has inferior edges which are the _________ (part of the ____ VFs)
ventricular/vestibular ligaments
false
quadrangular membrane’s superior edges are
deep structure of aryepiglottic folds
aryepiglottic folds are formed by
deep structure and mucous mem
conus elasticus connects
cricoid, thyroid, arytenoud cartilages
conus elasticus extends from
internal surface of cricoid
conus elasticus has 2 components
cricothryoid ligament and membrane
superior edges of conus elasticus are the
vocal ligaments - deep structure of TVFs
cricothyroid ligament is
a medial thickening in conus elasticus
cricothyroid ligaments connects
superior border of cricoid arch w inferior border of thyroid at its angle
cricothyroid membrane connects
cricothyroid ligament to the vocal processes of arytenoids
free superior edges of the cricothyroid membrane form the
vocal ligaments - part of TVFs
