翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Dental papilla ： ウィキペディア英語版 Dental papilla The dental papilla is a condensation of ectomesenchymal cells called odontoblasts, seen in histologic sections of a developing tooth. It lies below a cellular aggregation known as the enamel organ. The dental papilla appears after 8-10 weeks intra uteral life. The dental papilla gives rise to the dentin and pulp of a tooth. The enamel organ, dental papilla, and dental follicle together forms one unit, called the tooth germ. This is of importance because all the tissues of a tooth and its supporting structures form from these distinct cellular aggregations. ==See also== * Tooth development proceeds into three stages: the bud, cap and bell stage. these terms are descriptive of the morphology of the developing tooth germ but do not describe the significant functional changes that occur during development, such as morphogenesis and histodifferentiation. 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「Dental papilla」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.
