Muscles of the Body for Health Professionals, What Does the Risorius Muscle Do? Action - Closes the lips to narrow the oral opening. stroke, 2) those diagnosed as having a swallowing disorder, 3) those with inappropriate lip The orbicularis oris muscle is one ofthe orofacial muscles and plays an important role in swallowing and speech.This muscle is responsible for lip closure and prevents food from spilling out of the lips during swallowing 1). Inclusion in an NLM database does not imply endorsement of, or agreement with, Superficial to this stratum is a second, formed on either side by the caninus and triangularis, which cross each other at the angle of the mouth; those from the caninus passing to the lower lip, and those from the triangularis to the upper lip, along which they run, to be inserted into the skin near the median line. It is related to holding food due to general sphincteric activity along with other muscular loops of the oropharynx; this is known as the archaic part of the muscle. evaluated lip closure in the oral phase by using VFSSs and found a significant improvement This muscle closes the mouth and puckers the lips when it contracts. What is the action of the orbicularis oculi and orbicularis oris muscle? swallowing causes food to leak out of the lips and reduce intraoral pressure, negatively [3], In facial palsy: As the muscle receives nerve supply from the seventh cranial nerve, thus, injury to this nerve can result in paralysis of the muscle. Action: draws eyebrow medially, inferiorly, wrinkles skin of forehead vertically. For example, the orbicularis oris helps to control the contact made between the lips and the teeth in order to form different vowel and consonant sounds.

However, among orofacial muscle training, most of the previous studies are This muscle also helps in puckering the lips due to which it is sometimes known as the kissing muscle. The musicians also use this muscle when they play brass or woodwind instruments. In common language, the orbicularis oris is often referred to as the kissing muscle.

In addition to contributing to the fleshy and dermal portions of the lips, the orbicularis oris also provides the muscles fibers needed for speaking, swallowing, and eating. The facial nerve branches out into five branches, though the anatomy of the branching will vary among individuals, to innervate the variety of muscles located in the face.
