Omohyoid Muscle - Innervation

Innervation

The omohyoid is innervated by a branch of the cervical plexus, the ansa cervicalis, and mostly acts to stabilise the hyoid bone. Although the inferior belly of the omohyoid is innervated by branches of all three cervical rami (C1-C3) that make up the ansa cervicalis, the superior belly is innervated by the superior root of ansa cervicalis which contains only fibers from the first cervical spinal nerves (C1).
