They are also referred to as ''galactophores'', ''galactophorous ducts'', ''mammary ducts'', ''mamillary ducts'' and ''milk ducts''. They are the structures which carry milk toward the nipple in a lactating female. ==Structure== Lactiferous ducts are lined by a columnar epithelium supported by myoepithelial cells. When a woman is not lactating, the lactiferous duct is frequently blocked by a keratin plug. This plug prevents bacteria from entering the duct in non-lactating women. Prior to 2005, it was thought within the areola the lactiferous duct would dilate to form the lactiferous sinus in which milk supposedly accumulates between breastfeeding sessions. However new research suggests that lactiferous sinus does not exist. 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「Lactiferous duct」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.
