Thyroid Cartilage

   Also found in: Dictionary/thesaurus, Medical, Wikipedia 0.01 sec.
thyroid cartilage [′thī‚rȯid ‚kärt·lij]
(anatomy)
The largest of the laryngeal cartilages in humans and most other mammals, located anterior to the cricoid; in humans, it forms the Adam's apple.
Thyroid Cartilage 

the large unpaired cartilage of the larynx, which first appeared in vertebrate evolution in mammals.

The thyroid cartilage develops from the second and third gill arches. In cloacal animals the arches retain their independence, being joined to the copula, while in marsupial and placental animals they are fused, forming two quadrilateral lamellae that are united at an angle on the ventral side (in humans on the anterior side). In children and women these lamellae are united at an obtuse angle; in men they form an angular projection, known as the Adam’s apple. From the thyroid cartilage there pass the anterior cornua (in humans the superior cornua), in the direction of the hyoid bone (they are absent in pigs), and the posterior cornua (in humans the inferior cornua), which form a movable articulation with the cricoid cartilage.
