The other half aberrantly branched off and innervated the orbicularis oculi (eye muscle).
The orbicularis oculi closes the eye, while the contraction of the levator palpebrae muscle opens the eye.
It occurs when the hard palate is tickled, resulting in contraction of the orbicularis oris muscle and lowering of the upper lip.
In conjunction with orbicularis contraction, the mentalis muscle allows the lips to pout.
Deep/full thickness defects include the underlying muscles, primarily the orbicularis oris.
This is the kingdom of "emis orbicularis", the indigenous green turtle.
The orbicularis oculi muscles are often examined in patients with facial paralysis.
Four such muscles that were activated were the orbicularis oculi, zygomaticus, the corrugator, and levator.
