Answer :

Final answer:

Facial muscles produce expressions like smiles or frowns by moving the skin rather than bones. These expressions, influenced by certain muscle activity, can affect our emotions according to the facial feedback hypothesis. The key muscles involved include the buccinator and corrugator supercilii.

Explanation:

When facial muscles contract, they produce different kinds of facial expressions, such as smiling or frowning. The muscles responsible for facial expressions are unique among skeletal muscles because their insertions and origins are in the skin.

As a result, when facial muscles like the buccinator muscle or the corrugator supercilii contract, they move the skin rather than bones to form different expressions. For instance, the corrugator supercilii is the primary muscle for moving the eyebrows and can be felt in action when you raise your eyebrows in surprise or lower them in a frown.

Moreover, the facial feedback hypothesis suggests that our facial expressions can actually influence our emotional experiences. For example, smiling can potentially make you feel happier, while frowning might lead to less positive emotions. Emotional expressions such as happiness, surprise, sadness, and anger are associated with distinct facial muscle movements and are recognized as universal across different cultures.
