The facial muscles
are a group of striated muscles innervated by the facial nerve
that, among other things, control facial expression. These muscles are also called mimetic muscles.
The facial muscles are subcutaneous (just under the skin) muscles that control facial expression. They generally originate on bone, and insert on the skin of the face.
The facial muscles are innervated by cranial nerve VII, also known as the facial nerve. In contrast, the nearby masticatory muscles
are innervated by the mandibular nerve
, a branch of the trigeminal nerve
The facial muscles are derived from the second branchial/pharyngeal arch
List of muscles
The facial muscles include:
The platysma is innervated by the facial nerve. Although it is mostly in the neck, due to its common innervation it can sometimes also be considered a muscle of facial expression.
The stylohyoid muscle and posterior belly of the digastric muscle are also innervated by the facial nerve, but are not considered muscles of facial expression.
