The rectus capitis posterior minor (or rectus capitis posticus minor, both being Latin for ''lesser posterior straight muscle of the head'') arises by a narrow pointed tendon from the tubercle on the posterior arch of the atlas, and, widening as it ascends, is inserted into the medial part of the inferior nuchal line of the occipital bone and the surface between it and the foramen magnum, and also takes some attachment to the spinal dura mater. The synergists are the rectus capitus posterior major and obliquus capitis. Connective tissue bridges were noted at the atlanto-occipital joint between the rectus capitis posterior minor muscle and the dorsal spinal dura. Similar connective tissue connections of the rectus capitis posterior major have been reported recently as well.〔Anatomical Connection Between the Rectus Capitis Posterior Major and the Dura Mater. Scali F, Marsili ES, Pontell ME.http://journals.lww.com/spinejournal/Abstract/publishahead/Anatomical_Connection_Between_the_Rectus_Capitis.99006.aspx〕 The perpendicular arrangement of these fibers appears to restrict dural movement toward the spinal cord. The ligamentum nuchae was found to be continuous with the posterior cervical spinal dura and the lateral portion of the occipital bone. Anatomic structures innervated by cervical nerves C1-C3 have the potential to cause headache pain. Included are the joint complexes of the upper three cervical segments, the dura mater, and spinal cord. The dura-muscular, dura-ligamentous connections in the upper cervical spine and occipital areas may provide anatomic and physiologic answers to the cause of the cervicogenic headache. This proposal would further explain manipulation's efficacy in the treatment of cervicogenic headache. ==Additional images== File:Rectus capitis posterior minor muscle animation small.gif|Position of rectus capitis posterior minor muscle (shown in red).
