In humans, they are fused with the maxilla and the term "premaxilla" can also be used as a synonym for incisive bone. Other terms used for this structure include premaxillary bone or ''os premaxillare'', and intermaxillary bone or ''os intermaxillare''. ==Human anatomy== In humans, the premaxilla (or os incisivum) is the part of the maxilla which bears the incisor teeth, and encompasses the anterior nasal spine and alar region. In the nasal cavity, the premaxillary element projects higher than the maxillary element behind. The palatal portion of the premaxilla is a bony plate with a generally transverse orientation. The incisive foramen is bound anteriorly and laterally by the premaxilla and posteriorly by the palatine process of the maxilla. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Premaxilla」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
