The topographic structure which is externally visible and colloquially called the "Adam's apple" is caused by an anatomical structure of the thyroid cartilage called the laryngeal prominence or laryngeal protuberance protruding and forming a "bump" under the skin at the front of the throat.
Several species of waterfowl have a protuberance known as the basal knob at the top rear end of their bill. Examples are the knob-billed duck, the swan, and the Chinese goose. The exact purpose of basal knobs is unknown but they may serve as an indicator of health or sexual maturity. [8]
The mandibular symphysis divides below and encloses a triangular eminence, the mental protuberance, the base of which is depressed in the center but raised on either side to form the mental tubercle. The two mental tubercles along with the medial mental protuberance are collectively called the mental trigone.

It refers to the portion of the teeth that forms a convex protuberance at the cervical third of the anatomic crown. It represents the lingual or palatal developmental lobe of these teeth. [1] In zoology and palaeontology, cingulum refers to this feature only in the upper teeth. When this occurs in the lower teeth it is called the cingulid.
