|The cartilages of the larynx.|

It is composed of two plate-like laminae that come together on the anterior side of the cartilage to form a peak, called the laryngeal prominence. This prominence is often referred to as the "Adam's apple". The laryngeal prominence is obvious in both sexes, but it tends to be somewhat more robust in the adult male.
The lip of the thyroid cartilage just superior to the laryngeal prominence is called the thyroid notch or superior thyroid notch.
Layers and articulations
The two laminae that make up the main lateral, surfaces of the thyroid cartilage extend obliquely to cover either side of the trachea.
The thyroid cartilage forms the bulk of the anterior wall of the larynx, and serves to protect the vocal folds ("vocal cords") which are located directly behind it.
It also serves as an attachment for several laryngeal muscles.
