Origin

The sternohyoid muscle originates from the sternal end of the clavicle, along the posterior sternoclavicular ligaments, and the posterior surface of the manubrium of the sternum.

Insertion

The sternohyoid muscle courses in a superomedial direction towards the midline and inserts into the inferior border of the body of hyoid bone.

Key Features & Anatomical Relations

Variation is common and the sternohyoid may be absent or have additional fibrous slips. In particular, a separate portion with a clavicular attachment may be present, where it is named cleidohyoid (Tubbs, Shoja and Loukas, 2016).

Actions

The sternohyoid muscle depresses the hyoid bone after it has been elevated (Standring, 2016). It also fixes the hyoid bone in place with it opposes the actions of muscles that elevate the bone.
