Which hyoid muscle attaches to the scapula?

The omohyoid muscle is unique among the hyoid muscles because it specifically has a connection to the scapula. It originates from the superior border of the scapula, and it travels upward to insert into the body of the hyoid bone. This muscle plays a role in the movement of the hyoid bone as well as in stabilizing it during swallowing and speaking.

The other muscles listed—sternohyoid, sternothyroid, and thyrohyoid—do not have any attachment to the scapula. For example, the sternohyoid, sternothyroid, and thyrohyoid all originate from the sternum or thyroid cartilage and insert into the hyoid bone or thyroid cartilage. Therefore, the omohyoid is the only muscle in this group that connects to the scapula, making it the correct answer.
