What are the anatomical features of facial muscles?

Before talking about the features of facial muscles, let’s define what facial muscles are. Mimic muscles – muscles that express our emotions (facial expressions) and which perform protective reflexes (blinking): eyes, nostrils, mouth.
A distinctive feature of the facial muscles is that they perform minimal motor function. Such muscles are characterized by the following features: they are “woven” into the skin, being under the control of the nervous system, and when they contract, they narrow, their position changes along with the depth of the skin folds.
