|Anatomical terms of bone|
In human anatomy, the incisive bone or (Latin) os incisivum is the portion of the maxilla adjacent to the incisors. It is formed from the fusion of a pair of small cranial bones at the very tip of the jaws of many animals, usually bearing teeth, but not always. They are connected to the maxilla and the nasals. While Johann Wolfgang von Goethe was not the first one to discover the incisive bone in humans, he was the first to prove its presence across mammals. Hence, the incisive bone is also known as Goethe's bone.
In 1573, Volcher Coiter was the first to illustrate the incisive suture in humans. Pierre Marie Auguste Broussonet and Félix Vicq-d'Azyr were the first to describe the incisive bone as a separate bone within the skull in 1779 and 1780, respectively.
In the 1790s, Johann Wolfgang von Goethe began studying zoology, and formed the impression that all animals are similar, being bodies composed of vertebrae and their permutations. The human skull is one example of a metamorphosed vertebra, and within it, the intermaxillary bone rests as evidence linking the species to other animals.
