The sternohyoid muscle is a bilaterally paired, [1] long, [1] thin, [1] [2] narrow strap muscle [2] of the anterior neck. [1] It is one of the infrahyoid muscles. It is innervated by the ansa cervicalis. It acts to depress the hyoid bone. The sternohyoid muscle is a flat muscle located on both sides of the neck, part of the infrahyoid muscle group.
The omohyoid muscle is a muscle in the neck. It is one of the infrahyoid muscles. It consists of two bellies separated by an intermediate tendon. Its inferior belly is attached to the scapula; its superior belly is attached to the hyoid bone. Its intermediate tendon is anchored to the clavicle and first rib by a fascial sling.
The infrahyoid muscles, or strap muscles, are a group of four pairs of muscles in the anterior (frontal) part of the neck. [1] The four infrahyoid muscles are the sternohyoid, sternothyroid, thyrohyoid and omohyoid muscles. [1] Excluding the sternothyroid, the infrahyoid muscles either originate from or insert on to the hyoid bone. [2]
Branches of the ansa cervicalis innervate three of the four infrahyoid muscles: the sternothyroid, sternohyoid, and omohyoid muscles (note that the thyrohyoid muscle is the one infrahyoid muscle not innervated by the ansa cervicalis - it is instead innervated by cervical spinal nerve 1 via a separate thyrohyoid branch [2]: 582, 600 ).
The sternothyroid muscle (or sternothyroideus) is an infrahyoid muscle of the neck. [1] ... (inferior to the origin of the sternohyoid muscle), ...

Suprahyoid muscles - Digastric (Ant and post belly), mylohyoid, geniohyoid and stylohyoid. Infrahyoid muscles - Omohyoid, sternohyoid, sternothyroid, and thyrohyoid. Nerve supply
These muscles are grouped as the suprahyoid and infrahyoid muscles depending on if they are located superiorly or inferiorly to the hyoid bone. The suprahyoid muscles (stylohyoid, digastric, mylohyoid, geniohyoid) elevate the hyoid bone, while the infrahyoid muscles (omohyoid, sternohyoid, thyrohyoid, sternothyroid) depress it.
