It is situated at the front part of the medial wall of the orbit. It has two surfaces and four borders. Several bony landmarks of the lacrimal bone function in the process of lacrimation or crying. Specifically, the lacrimal bone helps form the nasolacrimal canal necessary for tear translocation. A depression on the anterior inferior portion of the bone, the lacrimal fossa, houses the membranous lacrimal sac. Tears or lacrimal fluid, from the lacrimal glands, collect in this sac during excessive lacrimation. The fluid then flows through the nasolacracrimal duct and into the nasopharynx. This drainage results in what is commonly referred to a runny nose during excessive crying or tear production.Injury or fracture of the lacrimal bone can result in posttraumatic obstruction of the lacrimal pathways. 〔http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3999077/〕 〔Anatomy and Physiology Saladin, 7e〕 ==Structure== 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「Lacrimal bone」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.
