In the human larynx, the cuneiform cartilages (from Latin: cuneus 'wedge' + forma 'form'; also known as cartilages of Wrisberg) are two small, elongated pieces of yellow elastic cartilage, placed one on either side, in the aryepiglottic fold. [1] The cuneiforms are paired cartilages that sit on top of and move with the arytenoids. [2]
Within the posterior part of each aryepiglottic fold exists a cuneiform cartilage which forms a whitish prominence, the cuneiform tubercle. [citation needed] The aryepiglottic folds contain the aryepiglottic muscles. They form the upper borders of the quadrangular membrane, and the lateral borders of the laryngeal inlet. [1]
The free superior border inclines posteriorly, forming the aryepiglottic ligament (the central component of the aryepiglottic fold within which the cuneiform cartilages are contained). Posteriorly, it contributes to the formation of the median corniculopharyngeal ligament.
The vocal folds are located within the larynx at the top of the trachea. They are attached at the back to the arytenoid cartilages, and at the front to the thyroid cartilage via Broyles ligament. They are part of the glottis. Their outer edges are attached to muscle in the larynx while their inner edges form an opening called the rima glottidis.
Laryngeal cartilages are cartilages which surround and protect the larynx. They form during embryonic development from pharyngeal arches. There are a total of nine laryngeal skeleton in humans: Thyroid cartilage - unpaired; Cricoid cartilage - unpaired; Epiglottis - unpaired; Arytenoid cartilages - paired; Corniculate cartilages - paired
The opening of larynx into pharynx known as the laryngeal inlet is about 4–5 centimeters in diameter. [1] The larynx houses the vocal cords, and manipulates pitch and volume, which is essential for phonation. It is situated just below where the tract of the pharynx splits into the trachea and the esophagus.
The area labeled "front" in each image is the Adam's Apple/Laryngeal Prominence. In a tracheal shave, superficial tissue at the front of the larynx is dissected and the general shape of the larynx's interior, along with the underlying vocal cords, are otherwise unaffected. In feminization laryngoplasty, the Adam's Apple is moved back even ...
The lateral cricoarytenoid (also anterior cricoarytenoid) is an intrinsic muscle of the larynx. It attaches at the cricoid cartilage anteriorly, and at the arytenoid cartilage of the same side posteriorly. It is innervated by the recurrent laryngeal nerve. It acts to close the rima glottidis, thus closing the airway.
