Cervical wall – ventral muscle (Infrahyoid muscle)


The English name for this muscle is the muscle of the shoulder and the hyoid bone. The term omo comes from the Greek word omos meaning “shoulder” and the term hyoid comes from its resemblance to the Greek letter upsilon (u), which is aspirated as hy. This is combined with the suffix eidos meaning “shape or form.”


Inferior belly arises from the superior border of the scapula at the scapular notch and the superior transverse scapular ligament


Passes via an intermediate tendon to the superior belly, which inserts on the inferior border of the hyoid body laterally


Depresses an elevated hyoid bone and assists in raising the cervical fascia during inspiration.

Ventral ramus via ansa cervicalis (C1) (superior belly); ventral ramus via the ansa cervicalis (C2 and C3) (inferior belly)
