The Posterior Scalene is a member of the Scalene Group, which is composed of the:

  • Anterior scalene
  • Middle scalene
  • Posterior scalene



  • The posterior scalene attaches from the transverse processes of the cervical spine to the second rib.
    • The superior attachments are onto the posterior tubercles of the transverse processes of C5-C7.



  • Laterally flexes the neck at the spinal joints.
