The mandible〔(Mandible on www.merriam-webster.com )〕 (from Latin ''mandibula'', "jawbone") or inferior maxillary bone is the largest, strongest and lowest bone in the face.〔Gray's Anatomy - The Anatomical Basis of Clinical Practice, 40th Edition, page: 530〕 It forms the lower jaw and holds the lower teeth in place. In the midline on the anterior surface of the mandible is a faint ridge, an indication of the mandibular symphysis, where the bone is formed by the fusion of right and left processes during mandibular development. Like other symphysis in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.〔 ==Structure== The mandible consists of: * a curved, horizontal portion, the ''body or ''base. (See body of mandible). * two perpendicular parts, the ''rami'', or ramus for each one, unite with the ends of the body nearly at right angles. (See ramus mandibulae). The angle formed at this junction is called gonial angle. * Alveolar process, the tooth bearing area of the mandible (upper part of the body of the mandible) * Condyle, superior (upper) and posterior projection from the ramus, which makes the temporomandibular joint with the temporal bone * Coronoid process, superior and anterior projection from the ramus. This provides attachment to the temporalis muscle The mandible articulates with the ''two'' temporal bones at the temporomandibular joints. 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「Human mandible」の詳細全文を読む スポンサード リンク
