    • omohyoid Pertaining to the shoulder-blade or scapula and to the lingual or hyoid bone; omohyoidean.
    • n omohyoid The omohyoid muscle. In man the omohyoid is a slender ribbon-like muscle which arises from the upper border of the scapula at the suprascapular notch, and is inserted into the body of the hyoid bone. It is a digastric muscle, having two fleshy bellies with an intervening tendon, which is bound down by an aponeurotic loop. The muscle passes obliquely downward and outward on the front and side of the neck, and is an important surgical landmark. It divides the anterior surgical triangle of the neck into a superior and inferior carotid triangle, in either of which the carotid artery may be reached; and after emerging from beneath the sternomastoid muscle it similarly divides the posterior triangle into the suboccipital and supraclavicular triangles. See first cut under muscle.
