Anatomy Muscles of the Face Diagram Biology Diagrams Facial muscles (Musculi faciales) The facial muscles, also called craniofacial muscles, are a group of about 20 flat skeletal muscles lying underneath the skin of the face and scalp. Most of them originate from the bones or fibrous structures of the skull and radiate to insert on the skin.. Contrary to the other skeletal muscles they are not surrounded by a fascia, with the exception of the
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. When they contract, the skin moves. These muscles also cause wrinkles at right angles to the muscles' action line. The muscles of the face are unique among groups of muscles in the body. While most muscles connect to and move only bones, facial muscles mostly connect bones to skin. These muscles, including the zygomaticus major and orbicularis oris, pull on the skin to produce a seemingly infinite number of facial expressions and to move the lips and cheeks Face muscle anatomy. Found situated around openings like the mouth, eyes and nose or stretched across the skull and neck, the facial muscles are a group of around 20 skeletal muscles which lie underneath the facial skin. The majority originate from the skull or fibrous structures, and connect to the skin through an elastic tendon.

What conditions and disorders can affect the facial muscles? To function, the facial muscles get signals from the brain via the facial nerve. But sometimes, they can't receive those signals properly. When the facial muscles cannot receive brain signals properly, that can cause: Droopy or sagging appearance in the face. Facial palsy (weakness).
Function: The Orbicularis oris muscle of the face helps to close the mouth and also, when this muscle contracts, the mouth puckers. 1 #2. Depressor Labii Inferioris Muscle of Face: This muscle of the face is located beneath the lower lip (mandible) underneath the mental foramen. Function: The Depressor labii inferioris muscle of the face helps to depress or lower the lower lip or bottom lip. The facial muscles are also known as the muscles of the facial expression or the mimetic muscles. These muscles are a group of approximately 20 superficial skeletal muscles of the face and scalp divided into five different groups according to their location and function. These groups include: Buccolabial (oral) group: Levator labii superioris, levator labii superioris alaeque nasi, risorius
