The Rectus capitis posterior major (or Rectus capitis posticus major, both being Latin for ''larger posterior straight muscle of the head'') arises by a pointed tendon from the spinous process of the axis, and, becoming broader as it ascends, is inserted into the lateral part of the inferior nuchal line of the occipital bone and the surface of the bone immediately below the line. In 2011, Scali et al., reported a soft tissue connection bridging from the rectus capitis posterior major to the cervical dura mater. Various clinical manifestations may be linked to this anatomical relationship. It has also been postulated that this connection serves as a monitor of dural tension along with the rectus capitis posterior minor. As the muscles of the two sides pass upward and lateralward, they leave between them a triangular space, in which the recti capitis posteriores minores are seen. Its main actions are to extend and rotate the atlanto-occipital joint. ==See also== * Atlanto-occipital joint * Rectus capitis lateralis * Rectus capitis posterior minor muscle * Rectus capitis anterior 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「Rectus capitis posterior major muscle」の詳細全文を読む スポンサード リンク
