Omohyoid muscle Omohyoid muscle The omohyoid muscle is a muscle that depresses the hyoid. It is located in the front of the neck and consists of two bellies separated by an intermediate tendon. Its superior belly serves as the most lateral member of the infrahyoid muscles, located lateral to both the sternothyroid and thyrohyoid muscles. Its name derives from the Greek "omos" meaning shoulder, giving one of its attachments, and "hyoid", giving the other attachment - the hyoid bone. It arises from the upper border of the scapula, and occasionally from the superior transverse scapular ligament which crosses the scapular notch, its
Anatomical terms of muscle set of fibers that perform the same function, and are usually supplied by different nerves for different set of fibers. For example, the tongue itself is a composite muscle made up of various components like longitudinal, transverse, horizontal muscles with different parts innervated having different nerve supply. The "insertion" and "origin" of a muscle are the two places where it is anchored, one at each end. The tissue of the attachment is called an "enthesis". The "origin" of a muscle is the bone, typically proximal, which has greater mass and is more stable during a contraction than a muscle's insertion.
