Mount the Cricoid cartilage on the trachea with the wide part of the ring facing a posterior direction and the lowered open part of the ring facing the anterior direction. The cricoid cartilage has facets/horns on both sides as well as on top to hold other connecting parts.
List the second step in creating the larynx.
Place the pyramid paired arytenoid cartilages on top of the cricoid with two corners facing each other creating a flat front and straight side with the back as the diagonal portion.
List the 3rd step in creating the larynx.
Place the horn-shaped paired corniculate cartilages on top of the arytenoid cartilages.
List the 4th step in creating the larynx.
Each of the two arytenoids has three corners. Label the anterior corners as the vocal processes. Label the lateral corners as the muscular processes.
List the 5th step in creating the larynx.
Place the thyroid cartilage on top of the cricoid cartilage. It is hinged at the points where the inferior facets/horns are located. The notch is anterior, the lamina are anterior and lateral, and the superior facets/horns are posterior superior.
List the 6th step in creating the larynx.
Attach the cricothyroid muscle. It has two paired sections: the pars recta (straight part runs vertically) and the pars obliques (slanted part runs to the side and back).
List the 7th step in creating the larynx.
Install the inner thyrovocalis muscles which run from the medial anterior part of the arytenoid cartilage (the vocal processes) to the throid notch.
List the 8th step in creating the larynx.
Install the thyromuscularis muscles. It runs laterally to the inner thyroid cartilage from the thyroid notch to the muscular processes of the arytenoid cartilage.
List the 9th step in creating the larynx.
Add the membraneous part of the vocal folds. They are semi-circles that extend from the thyroid notch to the arytenoids. Movement of the arytenoids causes the folds to abduct and adduct. The opening between the folds is referred to as the glottis.
Which cartilages in the larynx are most involved in adduction and abduction of the vocal folds?
The arytenoid cartilages.
A pocket in the laryngeal cavity between the true and false folds The true folds are inferior to the VM, and the false folds are superior to the VM.
Which of the following vocal folds are used for vocal phonation: the true vfs or the false vfs?
The true vocal folds.
The superior portion of the laryngeal cavity, and the entryway to the larynx. It is also above the ventricular vocal folds.
A membrane that is the region beneath the true vocal folds.
