Final answer:
The innervation of the omohyoid muscle is provided by the ansa cervicalis, which is a branch of the cervical plexus. The omohyoid muscle originates from the scapula and the first rib, and inserts on the hyoid bone.
Step-by-step explanation:
The innervation of the omohyoid muscle is provided by the ansa cervicalis, which is a branch of the cervical plexus. The superior belly of the omohyoid muscle originates from the scapula and the inferior belly originates from the first rib, both through tendons.
Its insertion is on the hyoid bone. The two bellies of the omohyoid muscle meet at an intermediate tendon, which is attached to the hyoid bone.
