orbicularis oris

Your orbicularis oris is sometimes known as the kissing muscle.

Her orbicularis oris stretched all out of shape.

Insertion: Skin at the corner of mouth and blending with orbicularis oris.

The Lip position would contract the orbicularis oris muscle, resulting in a frown.

The orbicularis oris muscles around his lips clamp his mouth into a thin straight line.

Since it pulls the eyebrows upward, it is the antagonist of the orbicularis oris.

In human anatomy, the orbicularis oris muscle is a complex of muscles in the lips that encircle the mouth.

This is your triangularis muscle pulling down the corners of your orbicularis oris muscle.

The lip pits extend into the orbicularis oris muscle, ending in blind sacs surrounded by mucous glands.

It occurs when the hard palate is tickled, resulting in contraction of the orbicularis oris muscle and lowering of the upper lip.

For example: compression to the facial nerve causes a lesion and the set of axons that innervates the orbicularis oris (mouth muscle) degenerate.

This time though, only 50% of the set of axons that innervate the orbicularis oris successfully reinnervate the original site.

As time progresses, it spreads to the whole lid, then to the orbicularis oris muscle around the lips, and buccinator muscle in the cheekbone area.

The most important muscle involved is the orbicularis oris muscle, which is used to pucker the lips and informally known as the kissing muscle.

This muscle arises from the oblique line of the mandible, and inserts on the skin of the lower lip, blending in with the orbicularis oris muscle.

Its fibers are inserted into the angle of the mouth, intermingling with those of the Zygomaticus, Triangularis, and Orbicularis oris.

In order for anterior to posterior transit of the bolus to occur, orbicularis oris contracts and adducts the lips to form a tight seal of the oral cavity.

The lower deep branches supply the Buccinator and Orbicularis oris, and join with filaments of the buccinator branch of the mandibular nerve.

For example, in modeling a human face edge loops should follow the orbicularis oculi muscle around the eyes and the orbicularis oris muscle around the mouth.

It follows a similar course along the edge of the upper lip, lying between the mucous membrane and the Orbicularis oris, and anastomoses with the artery of the opposite side.

In the head and neck, potential spaces are primarily defined by the complex attachment of muscles, especially mylohyoid, buccinator, masseter, medial pterygoid, superior constrictor and orbicularis oris.

It is a triangular mass with one vertex at the buccinators, one at the levator labii superioris alaeque nasi, and one at the orbicularis oris.

On either side of the symphysis, just below the incisor teeth, is a depression, the incisive fossa, which gives origin to the mentalis and a small portion of the orbicularis oris.
