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)
Depressor anguli oris: Draws down angle of mouth
Buccinator: Presses cheeks against teeth, pulls back angle of mouth (e.g., blowing a trumpet)

Muscles of Mastication

Pterygoideus lateralis: Opens mouth, moves lower jaw sideways
Pterygoideus medialis, temporalis, and Masseter: Closes jaws, clenches teeth tightly
