jawForward
pterygoids (and some masseter)·Pushes the lower jaw forward, shifting its position slightly ahead from its resting alignment.
jawLeft
pterygoids and temporalis·Moves the jaw to the side (in this case, left), shifting its position laterally.
jawRight
pterygoids and temporalis·Moves the jaw to the side (in this case, right), shifting its position laterally.
jawOpen
relaxation of masseter, temporalis, internal pterygoid; lateral pterygoid and suprahyoid muscles·AU26 moderately lowers the jaw through relaxation, while AU27 forcefully lowers it further.
mouthClose
orbicularis oris, masseter, temporalis, pterygoids, digastric·Brings the lips together by lowering the upper lip and raising the lower lip.
mouthDimpleLeft
buccinator·Draws the corners of the lips back against the teeth, tightening the mouth corners.
mouthDimpleRight
buccinator·Draws the corners of the lips back against the teeth, tightening the mouth.
mouthFrownLeft
depressor anguli oris·Draws the corners of the lips downward, creating a downturned lip shape.
mouthFrownRight
depressor anguli oris·Draws the corners of the lips downward, creating a slight frown or neutral expression.
mouthFunnel
orbicularis oris·Projects and spreads the lips outward, separating and fanning out the lips.
mouthLeft
N/A: a mixture of asymmetric muscle contractions on each side of the face
mouthLowerDownLeft
depressor labii inferioris·Draws the lower lip downward and laterally, stretching it down and to the sides.
mouthLowerDownRight
depressor labii inferioris·Draws the lower lip downward and laterally, stretching it down and to the sides.
mouthPressLeft
orbicularis oris·Presses the upper and lower lips firmly together.
mouthPressRight
orbicularis oris·Presses the upper and lower lips firmly together.
mouthPucker
incisivus labii superioris, incisivus labii inferioris·Draws the lip corners toward each other causing the fleshy part of the lips to protrude.
mouthRight
N/A: a mixture of asymmetric muscle contractions on each side of the face
mouthRollLower
orbicularis oris·The bottom portion of AU28 draws the lower lip into the mouth opening, wrapping it around the lower teeth.
mouthRollUpper
orbicularis oris·The top portion of AU28 draws the upper lip into the mouth opening, wrapping it around the upper teeth.
mouthShrugLower
mentalis·Pushes up the lower lip and chin area, causing the chin to protrude slightly and the lower lip to rise.
mouthShrugUpper
mentalis·Pushes up the upper lip and chin area, causing the chin to protrude slightly and the upper lip to rise.
mouthSmileLeft
zygomaticus major·Draws the corners of the lips upward, backward, and laterally, creating a stretched or elongated smile.
mouthSmileRight
zygomaticus major·Draws the corners of the lips upward, backward, and laterally, creating a stretched or elongated smile.
mouthStretchLeft
risorius·Draws the lip corners laterally, stretching the fleshy part of the lips.
mouthStretchRight
risorius·Draws the lip corners laterally, stretching the fleshy part of the lips.
mouthUpperUpLeft
levator labii superioris·AU10 lifts the top lip, more laterally than AU9 but more medially than AU11.
mouthUpperUpRight
levator labii superioris·AU10 lifts the upper lip, more laterally than AU9 but more medially than AU11.
cheekPuff
buccinator, orbicularis oris·Expands the cheeks by forcing air into them, causing them to puff outward.
cheekSquintLeft
orbicularis oculi, orbital portion·Tightens the outer rings of the eye orbit and squeezes the lateral eye corners.
cheekSquintRight
orbicularis oculi, orbital portion·Tightens the outer rings of the eye orbit and squeezes the lateral eye corners.
