Likewise, the nerve innervating frontalis muscle is called facial nerve VII or cranial nerve VII. You must sign in or sign up to start the quiz.
In humans, the occipitofrontalis only serves for facial expressions.
Unlike with other branches of the facial nerve, there is no redundancy in the innervation of the frontalis muscle.
Preserving the nerves crossing the STL requires an understanding of the complex fascial relationships at this line. The 4 extraocular muscles that control eye movement in the cardinal directions (along with their functions) are the superior rectus, inferior rectus, lateral rectus and medial rectus muscles.
