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]
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
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 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.
Just above the vocal process is a shallow depression, the oblong fovea of the arytenoid cartilage. Together they constitute the insertion for the vocalis muscle. [3] Vocal process granulomas are rare and benign lesions that occur in 0.9–2.7% of adults with a voice disorder. Most occurrences and forms of vocal process granulomas regress ...
The laryngeal cavity (cavity of the larynx) extends from the laryngeal inlet downwards to the lower border of the cricoid cartilage where it is continuous with that of the trachea. [12] [13] It is divided into two parts by the projection of the vocal folds, between which is a narrow triangular opening, the rima glottidis.
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.
Aditus of larynx. Borders. Its borders are formed by: the free curved edge of the epiglottis, anteriorly; the arytenoid cartilages, the corniculate cartilages, and ...
