The Sternohyoid is a member of the Infrahyoid Group, which is composed of the:
- Sternohyoid
- Sternothyroid
- Thyrohyoid
- Omohyoid
ATTACHMENTS:
- The sternohyoid attaches from the sternum to the hyoid bone.
ACTIONS:
- 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.
