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
Depressor supercilii muscle Depressor supercilii muscle The depressor Supercilii is an eye muscle of the human body. The nature of this muscle is in some dispute. Few printed anatomies include it (Netter, et al.) and many authorities consider it to be part of the orbicularis oculi muscle. On the other hand, many dermatologists, ophthalmologists and plastic surgeons hold that the depressor supercilii is a distinct muscle and has a definite, individual effect on the movement of the eyebrow and skin of the glabella. The depressor supercilii originates on the medial orbital rim, near the lacrimal bone, and inserts on the medial aspect of
