Larynx Dissection
1. When we began we saw the trachea, the aditus, vestibule, and the aryepiglottic folds.
a. The trachea is the tube-like structure that attaches to the cricoid, and brings oxygen into the lungs.
b. The esophagus is the structure on the posterior side of the structure, this structure brings the bolus into the stomach.
c. The aditus is the opening at the top of the structure
d. The vestibule
e. The aryepiglottic folds connect the front epiglottis cartilage to the arytenoid cartilage to create the top part of larynx. This was seen as two fold like structures, seen in the aditus.
2. After cutting through the muscular structures and removing the trachea the arytenoid cartilage, thyroid …show more content…
The arytenoid is superior to the cricoid and inferior to the thyroid cartilage. It is a set of two pieces of cartilage located in the larynx, which attaches to the true vocal folds. They are important for vocal sound.
c. The cricoid is the cartilage that surrounds the top of the trachea. The location is in the middle and center of the neck. This cartilage provides connection to different ligaments, cartilages, and muscles that open and shut the air passage and creates the production of sound.
3. After cutting through the muscular structures even more, different muscles appeared such as the cricothyroid, posterior cricoid arytenoid, transverse arytenoid, and the interaryenoids.
a. The cricothyroid originates on the cricoid cartilage and inserts on the thyroid cartilage. This muscle helps lengthen and tense the vocal cords.
b. The posterior cricoid arytenoid originates on the cricoid cartilage and inserts on the arytenoid cartilage. This muscle helps to abduct and laterally turns the arytenoid.
c. The transverse arytenoid originates on the posterior portion of the arytenoid cartilage and inserts onto the opposite side of the cartilage. This muscle adducts the arytenoid
