Test your knowledge with labeled diagrams Now that you've learned about the muscles of the face, it's time to test your memory and understanding. The best way to do this at the beginning of your revision is by using labeled diagrams. The human face is the most anterior portion of the human head. It refers to the area that extends from the superior margin of the forehead to the chin, and from one ear to another. The basic shape of the human face is determined by the underlying facial skeleton (i.e. viscerocranium ), the facial muscles and the amount of subcutaneous tissue. The facial muscles can broadly be categorised into three groups - orbital, nasal and oral. In this article, we shall look at the anatomy of the muscles of facial expression - their attachments, actions and clinical relevance. Fig 1 - Innervation to the muscles of facial expression via the facial nerve (CN VII) Orbital Group The facial muscles are striated muscles that link the skin of the face to the bone of the skull to perform important functions for daily life, including mastication and expression of emotion.

Key Terms. depressor labii inferioris: An analogous muscle that lowers the bottom lipEndFragment; Buccinator: This muscle is located between the upper and lower jaws in the cheek, deep to the other muscles of the face.; zygomatic: This muscle controls the cheeks to create smiles and frowns.; Procerus: The most superior of all facial muscles.; depressor anguli oris: This muscle is opposite to. 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. They are only found in mammals, although they derive from neural crest cells found in all vertebrates. The muscles of facial expression (also known as the mimetic muscles) can generally be divided into three main functional categories: orbital, nasal and oral. These muscles are all innervated by the facial nerve (CN VII).¹ These striated muscles broadly originate from the surface of the skull and insert onto facial skin.

The neck muscles, including the sternocleidomastoid and the trapezius, are responsible for the gross motor movement in the muscular system of the head and neck. They move the head in every direction, pulling the skull and jaw towards the shoulders, spine, and scapula. Working in pairs on the left and right sides of the body, these muscles.
