The muscle is directed superomedially from its origin to its insertion. The two muscles are separated by a considerable interval inferiorly, but usually converge by their mid-point and remain proximal until their superior insertion.[2]
The muscle may be absent, doubled, exhibit a clavicular slip (the cleidohyoideus), or interrupted by a tendinous intersection;[2] it sometimes presents a transverse tendinous inscription just distal to its origin.[citation needed]
Actions/movementsedit
The muscle depresses the hyoid bone when the bone is in an elevated position.[2]
Functionedit
The sternohyoid muscle performs a number of functions:
Section of the neck at about the level of the sixth cervical vertebra.
Posterior surface of sternum and costal cartilages, showing Transversus thoracis.
The fascia and middle thyroid veins. The veins here designated the inferior thyroid are called by Kocher the thyroidea ima.
