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. [2]
Muscles of head and neck. The Facial Action Coding System (FACS) is a system to taxonomize human facial movements by their appearance on the face, based on a system originally developed by a Swedish anatomist named Carl-Herman Hjortsjö. [1]
The zygomaticus major muscle is a muscle of the face. It arises from either zygomatic arch ; it inserts at the corner of the mouth. It is innervated by branches of the facial nerve (cranial nerve VII). It is a muscle of facial expression, which draws the angle of the mouth superiorly and posteriorly to allow one to smile. Bifid zygomaticus ...
During strength training, your muscles grow larger and stronger, adding myonuclei (control centers within individual muscle fibers that help regulate growth and repair), says Luke Carlson, CPT ...
The face changes over time, and features common in children or babies, such as prominent buccal fat-pads disappear over time, their role in the infant being to stabilize the cheeks during suckling. While the buccal fat-pads often diminish in size, the prominence of bones increase with age as they grow and develop. [1]
Growth sites are dependent on the growth centers for growth. Some examples include sutures of cranial vault, lateral cranial base and maxilla. Growth Centers is an area in the bone that controls the overall growth of the bone from its locations through different signaling mechanisms. Growth at these centers are genetically controlled. All ...
The levator labii superioris (pl.: levatores labii superioris, also called quadratus labii superioris, pl.: quadrati labii superioris) is a muscle of the human body used in facial expression. It is a broad sheet, the origin of which extends from the side of the nose to the zygomatic bone .
Damage to the marginal mandibular branch of the facial nerve may cause paralysis of the depressor anguli oris muscle. [1] This may contribute to an asymmetrical smile. [1] This may be corrected by resecting (cutting and removing) the depressor labii inferioris muscle, which has a more significant impact on smiling. [1]
