Mimetic muscles are a group of facial muscles responsible for controlling facial expressions. They allow us to convey emotions such as happiness, sadness, surprise, and anger through movements like smiling or frowning. These muscles are essential for non-verbal communication and play a significant role in social interactions. These muscles are primarily innervated by the facial nerve, which enables their precise movements. The main mimetic muscles include the orbicularis oculi, responsible for closing the eyes, and the zygomaticus major, which helps in smiling. Understanding these muscles is important in fields like anatomy and cosmetic surgery.
