What are the three points of the triangular bony chin known as?

The three points of the triangular bony chin are referred to as the mental tubercles, which are paired structures that contribute to the shape of the chin. These tubercles are located laterally on the body of the mandible and provide a distinctly pointed appearance to the chin area. Together, they form an important anatomical landmark and are significant in various surgical procedures, as well as in understanding facial structure in the fields of anatomy and mortuary science.

While the incisive fossa is also mentioned, it serves as a depression on the mandible located between the mental tubercles rather than being part of the defining points of the chin's structure. The other choices include structures that are not related to the triangular shape of the chin, such as the coronoid process and temporalis, which are associated with the mandible's movement and muscle attachment, rather than forming its bony contour. The superciliary arch and zygomatic arch refer to parts of the frontal and zygomatic bones, respectively, and do not pertain to the chin, while the mental protuberance specifically refers to the prominent part of the chin but does not encompass the full definition of the three points that make up its triangular shape.
