Larynx extras

quadrangular membrane

fibro-elastic sheet spanning the space between the lateral margins of the epiglottis and the arytenoid cartilages

vestibular ligaments

the inferior most extent of the quadrangular membrane form the ______ ______

vestibular (false vocal) folds

the vestibular ligaments are covered by mucosa to form the _____ _____

vestibular (false vocal) folds

these folds play an important role in protecting the airway and may also be used to produce harmonic tone in singing

quadrangular membrane

this is an important funnel for air that is inhaled

conus elasticus

fibro-elastic sheet that shapes the walls of the larynx as a funnel between the cricoid and thyroid cartilages

cricothyroid membrane

the inferior extent of the conus elasticus is made up of the ____ _____

vocal ligaments

the superior most aspects of the conus elasticus are the _____ _____

cricothyroid ligament

the anteromedial aspect of the conus elasticus is the (median) ______ _______

conus elasticus

this is an important funnel for air that is exhaled

laryngeal inlet

most superior

opening into larynx

laryngeal vestibule

2nd most superior

transitional area between the inlet and deeper larynx

rima vestibuli

3rd most superior

space between the vestibular folds

rima glottidis

5th most superior

spaces between the vocal folds

glottis

vocal folds + rima glottidis

affects voice modulation through expansion or contraction

laryngeal ventricle

4th most superior

space between the vestibular and vocal folds

separates the quadrangular membranes from the conus elasticus

infraglottic cavity

most inferior

narrows and continues inferiorly as the trachea

vestibular (false vocal) folds

these folds attach from the arytenoid cartilages to the thyroid cartilage

vestibular (false vocal) folds

these folds are formed by the vestibular ligament located on the free inferior edge of the quadrangular membrane with the overlying mucosa

vestibular (false vocal) folds

these function to protect the airway and vocal folds

vocal folds

these folds originate on the posterior aspect of the thyroid cartilage and run posteriorly to attach to the vocal processes f the arytenoid cartilages

vocal ligaments

these ligaments are formed by the free superior edge of the conus elasticus in the larynx (create folds when covered by mucosa)

vocal folds

these folds vibrate as air is exhaled and create varying sounds based on their position
