It is named after its two attachments near the molar teeth ("''mylo''" comes from the Greek word for "molar").〔http://www.anatomy.usyd.edu.au/glossary/glossary.cgi?page=m〕 These muscles are mesodermal in embryologic origin. The mylohyoid muscle is derived from the first pharyngeal arch. ==Structure== The mylohyoid muscle is flat and triangular, and is situated immediately superior to the anterior belly of the digastric muscle. It is a pharyngeal muscle (derived from the first pharyngeal arch) and classified as one of the suprahyoid muscles. Together, the paired mylohyoid muscles form a muscular floor for the oral cavity of the mouth. The two mylohyoid muscles arise from the mandible at the mylohyoid line, which extends from the mandibular symphysis in front to the last molar tooth behind. The posterior fibers pass inferomedially and insert at anterior surface of the hyoid bone. The medial fibres of the two mylohyoid muscles unite in a midline raphe (where the two muscles intermesh). The mylohyoid muscle separates the sublingual space from the submandibular space, which communicate in a lateral gap between the mylohyoid and geniohyoid muscles. The submandibular gland wraps around the edges of the mylohyoid, and is divided into superficial and deep lobes above and below the muscle. 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「Mylohyoid muscle」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.
