Anatomical terms of bone

In anatomy, especially human anatomy, the incisive bone or (Latin) os incisivum is the portion of the maxilla adjacent to the incisors. It is 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.

The term premaxilla can also be used to refer to the incisive bone, and is much more commonly used to refer to this structure in non-human species. Yet other terms include premaxillary bone, os premaxillare, intermaxillary bone, and os intermaxillare.
