The '''Stylohyoid muscle''' is a slender [[muscle]], lying in front of, and above the posterior belly of the [[digastric muscle]]. It shares this muscle's innervation by the [[facial nerve]].
==Origin and insertion==
It arises from the back and lateral surface of the [[styloid process (temporal)|styloid process]] of the [[temporal bone]], near the base; and, passing downward and forward, is inserted into the body of the [[hyoid bone]], at its junction with the greater cornu, and just above the [[Omohyoideus]]. It thus belongs to the group of [[suprahyoid muscles]].
It is perforated, near its insertion, by the tendon of the [[Digastricus]].
==Variations==
It may be absent or doubled, lie beneath the [[carotid artery]], or be inserted into the [[Omohyoideus]], [[Thyreohyoideus]], or [[Mylohyoideus]].
