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 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 .

Cartilage in the second pharyngeal arch is referred to as Reichert's cartilage and contributes to many structures in the fully developed adult. [14] In contrast to the Meckel's cartilage of the first pharyngeal arch it does not constitute a continuous element, and instead is composed of two distinct cartilaginous segments joined by a faint ...

Larynx showing vocal ligaments. The vibratory portion of the vocal fold in the anterior glottis is connected to the thyroid cartilage anteriorly by the macula flava and anterior commissure tendon, or Broyles' ligament. Posteriorly, this vibratory portion is connected to the vocal process of the arytenoid cartilage by the posterior macula flava.
The thyroid cartilage is a hyaline cartilage structure that sits in front of the larynx and above the thyroid gland. The cartilage is composed of two halves, which meet in the middle at a peak called the laryngeal prominence, also called the Adam's apple. [1] In the midline above the prominence is the superior thyroid notch.
The Human Cell Atlas project, which started in 2016, had as one of its goals to "catalog all cell types (for example, immune cells or brain cells) and sub-types in the human body". [13] By 2018, the Human Cell Atlas description based the project on the assumption that "our characterization of the hundreds of types and subtypes of cells in the ...
