The facial muscles are a group of striated skeletal muscles supplied by the facial nerve cranial nerve VII that, among other things, control facial expression. These muscles are also called mimetic muscles. The facial muscles are just under the skin subcutaneous muscles that control facial expression. They generally originate from the surface of the skull bone rarely the fascia , and insert on the skin of the face.
A facial expression is one or more motions or positions of the muscles beneath the skin of the face. According to one set of controversial theories, these movements convey the emotional state of an individual to observers. Facial expressions are a form of nonverbal communication. They are a primary means of conveying social information between humans , but they also occur in most other mammals and some other animal species. Humans can adopt a facial expression voluntarily or involuntarily, and the neural mechanisms responsible for controlling the expression differ in each case. Voluntary facial expressions are often socially conditioned and follow a cortical route in the brain. Conversely, involuntary facial expressions are believed to be innate and follow a subcortical route in the brain.

Asked by Wiki User. There are several muscles used in facial expressions: Epicranius, Orbicularis oculi, Buccinator, Zygomaticus major and minor, and Platysma. They are facial muscles innervated by the facial nerve that, among other things, control facial expression. The facial muscles are innervated by facial nerve cranial nerve VII. In contrast, the nearby masticatory muscles are innervated by the mandibular nerve, a branch of thetrigeminal nerve V.
