The nine cartilages of the larynx, including the cricoid, thyroid and epiglottic, and two each of arytenoid, corniculate and cuneiform.

Thin leaf-shaped cartilage, covered with mucous membrane, at the root of the tongue, which folds back over the entrance to the larynx, covering it, during the act of swallowing.

One of a pair of small pyramidal cartilages that articulate with the lamina of the cricoid cartilage. The corresponding vocal ligament and several muscles are attached to it.

The small thick cartilage that forms the lower and posterior parts of the laryngeal wall.

The largest cartilage of the larynx consisting of two laminae fusing anteriorly at an acute angle in the midline of the neck. The point of fusion forms a subcutaneous projection known as the Adam's apple.

The intrinsic muscles of the larynx are the aryepiglottic(us), arytenoid(eus), cricoarytenoid(eus), cricothyroid(eus), thyroarytenoid(eus), thyroepiglottic(us) and vocal(is).

A glandular epithelial cell or a unicellular gland. Goblet cells secrete MUCUS. They are scattered in the epithelial linings of many organs, especially the SMALL INTESTINE and the RESPIRATORY TRACT.

An irregularly shaped, musculocartilaginous tubular structure, lined with mucous membrane, located at the top of the trachea and below the root of the tongue and the hyoid bone. It is the essential sphincter guarding the entrance into the trachea and functioning secondarily as the organ of voice.

The vocal apparatus of the larynx, consisting of the true vocal cords (plica vocalis) and the opening between them (rima glottidis).

The folds of mucous membrane along either wall of the larynx from the angle between the laminae of the thyroid cartilage to the vocal process of the arytenoid cartilage.
