Functional Anatomy of Facial Muscles. An Injector Eye. Part One.pptx
The facial muscles are a group of about 20 muscles that lie under the skin and control facial expressions. They also help with chewing and moving the ears, eyes, nose, and mouth. The facial muscles are innervated by the facial nerve (CN VII) and supplied by the facial artery. The facial muscles can be divided into five groups: muscles of the mouth, nose, eyelid, cranium, neck, and external ear. Facial muscles are responsible for facial expressions, but they also influence the shape and contour of the face over time. The constant activity of facial muscles, combined with their eventual reduction in strength, changes the appearance of the face. They also influence the distribution and loss of subcutaneous fat, contributing to the facial volume. The effect of facial muscles on aesthetics and aging of the face is a complex topic that involves various factors. The author recommends investigating the relationship between adipose tissue facial muscles further.
