Stylohyoid muscle greater cornu, and just superior the omohyoid muscle. It thus belongs to the group of suprahyoid muscles. When contracted, it elevates the hyoid, this action is primarily brought about during swallowing. It is perforated, near its insertion, by the intermediate tendon of the digastric muscle. A branch from the extracranial path of the facial nerve (CN VII) innervates the Stylohyoid muscle. It may be absent or doubled, lie beneath the carotid artery, or be inserted into the omohyoid, or mylohyoid muscles. The stylohyoid muscle elevates and retracts hyoid bone.Initiates a swallowing action by pulling the hyoid bone in a posterior
Frontalis muscle paler in color. It is located on the front of the head. The muscle has no bony attachments. Its medial fibers are continuous with those of the procerus; its immediate fibers blend with the corrugator and orbicularis oculi muscles, thus attached to the skin of the eyebrows; and its lateral fibers are also blended with the latter muscle over the zygomatic process of the frontal bone. From these attachments the fibers are directed upward, and join the galea aponeurotica below the coronal suture. The medial margins of the frontalis muscles are joined together for some distance above the root of
