  Orbicularis Oris Muscle   (Site not responding. Last check: 2007-09-20)
The orbicularis oris is a sphincter muscle that encircles the mouth.
It lies between the skin and the mucous membranes of the lips, extending upward to the nose and down to the region between the lower lip and chin.
It is sometimes called the kissing muscle because it causes the lips to close and pucker.

 Orbicularis oris muscle - Wikipedia, the free encyclopedia
It is sometimes known as the kissing muscle because it is used to pucker the lips.
In human anatomy, the orbicularis oris muscle is the sphincter muscle around the mouth.
The Orbicularis oris is not a simple sphincter muscle like the Orbicularis oculi; it consists of numerous strata of muscular fibers surrounding the orifice of the mouth but having different direction.

The lips (A.S. lippa) are fleshy folds, surrounding the opening of the mouth, and are formed, from without inward, by skin, superficial fascia, orbicularis oris muscle, submucous tissue, containing numerous labial glands about the size of a small pea, and mucous membrane.
In the deeper part of each lip lies the coronary artery, while in the mid-line is a reflection of the mucous membrane on to the gum forming the fraenum labii.
Above the gland reaches to the zygoma, and below to the level of the angle of the jaw, where a strong process of the deep cervical fascia, called the stylo-mandibular ligament, separates it from the submaxillary gland; indeed the parotid is often described as lying in a bag formed by deep cervical fascia.

The cheek region is subdivided by the anterior prominence of the clenched masseter muscle.
Muscles affecting the forehead and eyebrow include the frontalis muscle, which creates the horizontal wrinkles on the forehead and assists with eyebrow elevation, and the corrugators and procerus muscles, which are antagonistic muscles on the forehead.
The major functions of the orbicularis oris muscle are to pull the lips against the teeth, to draw the lips together, to pull the corners of the mouth together, and to pucker.

 Orbicularis Oris of the Face and Mouth   (Site not responding. Last check: 2007-09-20)
Orbicularis oris is the sphincter muscle around the mouth, forming much of the tissue of the lips.
This muscle acts to shape and control the size of the mouth opening and is important for creating the lip positions and movements during speech.
Orbicularis oris is innervated by the lower zygomatic, buccal, and mandibular branches of the facial nerve (VII) and is supplied with blood by the facial artery.

The orbicularis muscle was found ruptured with its end joined by a fibrous a bloodless band Fig.2) similar to the fibrous union usually found in ruptured tendons.
Perhaps this may be due to some recuperation of the muscle fibers or to the ability of the lips to adapt to new local conditions.
Presumably a muscle rupture occurred, and the fibrous or scar tissue interposition produced a lengthening of the circumference of the orbicularis oris.

 Mouth Muscle Exercise
The exercise for the orbicularis oris, the circular muscle around the mouth, is not a gentle one.
In fact, stretching of the facial muscles may not be good for the overlying skin.
It is isotonic because there is a change in the length of the muscle; it is isometric because you will hold the contraction of each rep for a second or two - in other words, the muscle will maintain a constant length as you hold the contraction.

The orbicularis oris muscle may be divided only at the lower portion of the lip while the rest of the muscle and skin remain intact.
In many cases of partial unilateral cleft lip, the orbicularis oris muscle may be divided completely, creating a groove of the skin.
Separation of the muscle may cause it to bulge on both sides of the cleft.

In complete cleft lip, the asymmetric division of the orbicularis oris muscle causes a functional imbalance which impairs the function of the lip created by the abnormal attachment of the muscle on each side of the cleft.
To surgically repair the cleft and to provide for normal facial movement, the surgeon must free the muscle on each side of the cleft from its abnormal attachment and reconstruct it in a normal, horizontal configuration.
