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
Occipitofrontalis muscle Occipitofrontalis muscle The occipitofrontalis muscle (epicranius muscle) is a muscle which covers parts of the skull. It consists of two parts or bellies: The occipital belly, near the occipital bone, and the frontal belly, near the frontal bone. In humans, the occipitofrontalis only serves for facial expressions. Some sources consider the occipital and frontal bellies to be two distinct muscles. However, Terminologia Anatomica currently classifies it as a single muscle, and also includes the temporoparietalis muscle as part of the epicranius. The occipitofrontalis muscle receives blood from several arteries. The frontal belly receives blood from the supraorbital and supratrochlear arteries,
