Ansa cervicalis

The ansa cervicalis (or ansa hypoglossi in older literature) is a loop of nerves that are part of the cervical plexus.

Branches from the ansa cervicalis innervate all but one of the infrahyoid muscles, including the sternohyoid muscle, the sternothyroid muscle, and the omohyoid muscle. The thyrohyoid muscle is innervated by C1 only.

Roots

Two roots make up the ansa cervicalis.
