The sternohyoid of the infrahyoid group. The omohyoid (also of the infrahyoid group) has been ghosted in on the left side.

The Sternohyoid is a member of the Infrahyoid Group, which is composed of the:

  • Sternohyoid
  • Sternothyroid
  • Thyrohyoid
  • Omohyoid



  • The sternohyoid attaches from the sternum to the hyoid bone.



  • Depresses the hyoid bone.
  • Flexes the neck at the spinal joints.
  • Assists, via stabilization of the hyoid bone, depression of the mandible at the temporomandibular joints (TMJs).


NOTE: The carotid sinus of the common carotid artery runs slightly lateral to the sternohyoid, so manual therapy in this region should be done judiciously.
