"The sternohyoid muscles are innervated by the anterior rami of C1 – C3 (predominantly C2 and C3) through the ansa cervicalis of the cervical plexus."
"The sternohyoid muscle is an infrahyoid muscle of the neck that is innervated by the ansa cervicalis of the cervical plexus receiving fibres from the ventral rami of C1-C3 spinal nerves. The sternohyoid is a paired, flat strap of muscle that serves to fix the hyoid bone as well as depressing the larynx in phonation and in the terminal phase of swallowing."
