The muscles of facial expression primarily insert into the skin and tissues of the face, rather than onto bones. They attach to various structures, including the skin around the eyes, mouth, and forehead, allowing for a wide range of movements that convey emotions. This unique insertion point enables the facial muscles to create expressions such as smiling, frowning, and raising eyebrows.

What cranial nerve is responsible for muscles of facial expression?

What two muscles of facial expression that are circular and their function?
The two facial muscles that are circular are the Orbicularis Oculi(around eye), and the Orbicularis Oris(around mouth).

This action also engages the orbicularis oculi muscles around the eyes, creating crow's feet or eye wrinkles. Additionally, smiling can help relax other facial muscles and release tension, contributing to a more positive facial expression.
Which muscle does the facial nerve passes through?
The facial nerve (cranial nerve VII) passes through the parotid gland, but it does not innervate it. Instead, it branches within the gland to supply the muscles of facial expression. Additionally, it travels through the stylohyoid and digastric muscles before reaching the face.
