"The sternothyroid 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 sternothyroid 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."
"innervation: anterior rami of C1-C3 spinal nerves through the ansa cervicalis"
"The sternothyroid muscles are innervated by the anterior rami of C1-C3 (predominantly C2 and C3) through the ansa cervicalis of the cervical plexus."
