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
Procerus muscle Procerus muscle The procerus muscle (or pyramidalis nasi) is a small pyramidal slip of muscle deep to the superior orbital nerve, artery and vein. "Procerus" is Latin, meaning tall or extended. The procerus arises by tendinous fibers from the fascia covering the lower part of the nasal bone and upper part of the lateral nasal cartilage. It is inserted into the skin over the lower part of the forehead between the two eyebrows on either side of the midline, its fibers merging with those of the frontalis. The procerus helps to pull that part of the skin between the eyebrows
