Facial Muscles
- Frontalis: Raises eyebrows, wrinkles forehead (e.g., surprise, fright)
- Corrugator supercilii: Draws eyebrows together (e.g., frowning)
- Procerus: Pulls skin of nose upward (e.g., anger)
- Nasalis (alar portion): Widens nostrils (e.g., forced/difficult breathing)
- Nasalis (transverse portion): Draws the nose downward narrowing the nostrils
- Orbicularis oculi (orbital part): Closes eyelids tightly
- Orbicularis oculi (palpebral part): Closes eyelids gently
- Levator palpebrae superioris: Raises upper eyelid
- Rectus medialis oculi and rectus lateralis oculi: Move the eye horizontally
- Risorius: Draws angle of mouth backward
- Zygomaticus major: Draws angle of mouth upward and outward (e.g., smiling)
- Levator labii superioris: Raises and protrudes upper lip (e.g., showing upper gum)
- Depressor labii inferioris and platysma: Draws lower lip and angle of mouth downward (e.g., sadness)
- Mentalis: Raises chin skin and protrudes lower lip (e.g., pouting)
- Orbicularis oris: Closes and protrudes lips (e.g., whistling)
