fa·cial mus·cles

[TA]
the numerous muscles supplied by the facial nerve that are attached to and move the skin of the face. Terminologia Anatomica includes the buccinator muscle in this group because of its innervation and embryonic origin, even though it functions primarily in mastication.
Synonym(s): musculi faciei [TA], mimetic muscles, muscles of facial expression
