The risorius muscle is a narrow bundle of fibers, broadest at its origin, but varies much in its size and form. It arises in the fascia over the parotid gland and, passing horizontally forward, superficial to the platysma, inserts onto the skin at the angle of the mouth. The risorius muscle retracts the angle of the mouth to produce a smile, albeit an insincere-looking one that does not involve the skin around the eyes. This Risorius Muscle Medical PowerPoint Theme or template is overall colored Green, Light. The download includes a Title slide that's visually coordinated with the remaining slides in the template.
