Musculus omohyoideus

The video tutorial explains the omohyoid muscle, also known as the shoulder blade tongue leg muscle. It is part of the infra hyoid muscles responsible for throat, head, and tongue bone movement. The omohyoid consists of two muscular bellies and connects to various neck structures. It plays a role in swallowing and larynx movement, supporting blood flow from the head to the superior vena cava. The muscle is innervated by the cervical plexus, with fibers from spinal segments C1 to C3.

Explain the relationship between the omohyoid muscle and the cervical plexus.

How does the omohyoid muscle support the return of blood from the head?
