Lesson 3 Anatomy

-Stretches across the space between the greater cornu of the hyoid and lateral thyroid cartilage
-Membrane thickens medially and laterally
-Triticeal cartilage is embedded in lateral thyrohyoid ligament

Ligaments: _______ Membrane

-Forms the support structure for the cavity of the larynx as well as the vocal folds themselves

Ligaments: Parts of the Fibroelastic Membrane

-Arepiglottic Folds and Vestibular fold/False vocal fold

Ligaments: Parts of the Fibroelastic Membrane

Vocal Ligament (upward extension of the ___ ____)

Laryngeal Membranes: 

-Runs from the arytenoids to the epiglottis and thyroid cartilage
-Free in the superior and inferior margins, but attaches to the arytenoid cartilage and epiglottis

Quadrangular membranes: 

-the free superior margins form the ____ folds

Quadrangular membranes:

-The free inferior margins form the _____ fold (the false vocal folds)

Laryngeal Membranes:

-Run from the side of the epiglottis to the arytenoid apex
-Forms the upper margin of quadrangular membrane

Laryngeal Membranes:

-can also be called cricothyroid membrane

-elastic portion of the larynx that connects the cricoid with thyroid and arytenoid cartilage

-the upward free extension of the ___ ____ form the vocal ligament (true vocal fold)

Laryngeal Ligament:

-Upper portion of the conus elasticus

-Two strong bands enclosed within the vocal folds

-Attaches at the front angle of the thyroid cartilage and extends to the vocal process of the arytenoid

Laryngeal Ligaments:

-Connects lower border of cricoid cartilage with upper border of the first tracheal ring

Laryngeal Ligaments:

-Connects epiglottis to the interior portion of the thyroid cartilage, near the thyroid notch

The Laryngeal cavity is composed of (All Virgins Lie Greatly)

Laryngeal Cavity:

-Entrance to the larynx from the pharynx above

Laryngeal Cavity:

-Cavity between the aditus and the ventricular folds (false vocal folds)

Laryngeal Cavity:

-Space between margins of false vocal folds and true vocal folds

Laryngeal Cavity:

Space between the vocal folds inferior to the ventricle and superior to the conus elasticus

Laryngeal Cavity:

-Most important laryngeal space for speech
-____ area is variable depending on the configuration of the vocal folds

Vocal Folds:

- Combines free edge of conus elasticus and the vocalis muscle
-Vibrate to produce sound
-White in appearance due to lack of vascular supply

Vocal Folds:

-Combination of the ventricular ligament and overlying epithelial tissue
-Do NOT vibrate to produce sound
