Omohyoid Muscle Of A Male As, Anterior View

Description

Running obliquely across the anterior cervical region, the omohyoid muscle is presented with both its inferior belly and superior belly, linked by the intermediate tendon deep to the sternocleidomastoid. The inferior belly arises from the superior border of the scapula near the suprascapular notch and courses anterosuperomedially toward the clavicle, while the superior belly continues from the tendon to insert on the inferior border of the hyoid bone, lateral to the sternohyoid. Adjacent landmarks in this male head and upper torso view include the paired sternocleidomastoid muscles, the clavicles, upper ribs, cervical vertebrae, and the craniofacial skeleton. For surgical anatomy of the neck, the omohyoid matters because its superior belly forms a surface landmark that helps define the carotid triangle and its inferior belly crosses near the lower neck where central venous access and lymph node dissection are performed. Its intermediate tendon is tethered to the clavicle by a fascial sling, so contraction can tense the cervical fascia and influence the contour of the supraclavicular fossa. Small muscle, big map. Educators often pair this anterior perspective with diagrams of the anterior triangle subdivisions, the ansa cervicalis loop on the carotid sheath, and fascial layer dissections that explain why the omohyoid can be encountered unexpectedly during tracheostomy exposure or level III and IV neck dissections.
