L2 - T/F

The lower margin of the base is attached to the upper margin of the cricoid cartilage.

The upper free margin of the cricothyroid membrane connects the vocal process of the arytenoid to the inner surface of the thyroid cartilage.

The upper margin of the base mucosa continues upward to the saccule of the larynx.

When a ligament connects two cartilages of the larynx it is intrinsic, when it connects a cartilage of the larynx to another structure it is extrinsic.

The laryngeal inlet faces backward and upward and opens into the laryngeal part of the pharynx.

The laryngeal cavity extends from the laryngeal inlet to the lower border of the cricoid cartilage.

The supraglottic part of the laryngeal cavity is called the vestibule/aditus.

The lower part of the laryngeal cavity is formed by the inner surface of the cricothyroid ligament and the cricoid cartilage.

The saccule of the larynx contains mucous glands that moisten the mucosal surface of the vocal fold with their secretions.

The vocal folds vibrate aerodynamically over the body resulting in sound production.

True or false: All structures in the larynx are lined with Pseudostratified ciliated columnar epithelium?

True or false: The surface of vocal folds, aryepiglottic folds, anterior surface and upper half of posterior surface of epiglottis are covered with stratified squamous epithelium?

True or false: The deposition of Fibrous tissue in the subepithelial area changes the classification from membrane to ligament?

True or false: The classification of an area covered on the surface by epithelium from membrane to ligament depends on the histology of the sub epithelium?

True or false: The Quadrangular (4) membrane extends between the epiglottis and the arytenoid cartilages?

True or false: The anterior margin of the Quadrangular membrane is attached to the lateral edge of the epiglottis?

True or false: The posterior margin of the Quadrangular membrane is attached to the arytenoid cartilages?

True or false: The upper margin of the Quadrangular membrane is reflected on a thickening in the sub-epithelium of the quadrangular membrane extending between the arytenoid cartilage and the epiglottis called the Aryepiglottic fold?

True or false: The lower margin of the Quadrangular membrane is reflected on a thickening in the sub-epithelium of the quadrangular membrane extending between the arytenoid cartilage and the thyroid cartilage called the vestibular fold (false vocal fold)?

True or false: The mucosa continues downward after reflection to the saccule of the larynx?
