SPHINCTER ORIS Meaning and
Definition
-
The term "sphincter oris" refers to a specific anatomical structure present in the human body. It is derived from the Latin words "sphincter," meaning "a band that encircles," and "oris," meaning "mouth." In simple terms, the sphincter oris is more commonly known as the "oral sphincter" or the "mouth sphincter."
The sphincter oris is a circular muscle that surrounds the opening of the mouth, also known as the oral cavity. It is responsible for controlling the movements of the mouth, particularly during the process of chewing and swallowing. This muscle is crucial in maintaining the proper function and coordination of the various structures involved in eating and speaking.
During the process of eating or drinking, the sphincter oris contracts and relaxes in a coordinated manner, allowing the mouth to open and close. Its contraction helps in the proper crushing and grinding of food by moving it between the upper and lower dental arches. This muscle also assists in maintaining the seal of the mouth, preventing the oral contents from leaking out.
In addition, the sphincter oris is important for proper speech production. It plays a crucial role in shaping the sounds and movements of the lips, contributing to the articulation of speech sounds and communication.
Overall, the sphincter oris is an essential muscle that aids in the effective functioning of the mouth. Its precise control and coordination are essential for activities such as eating, swallowing, and speaking.

Etymology of SPHINCTER ORIS
The word "sphincter oris" has its origins in Latin. "Sphincter" is derived from the Greek word "sphíngktēr", meaning "tight binder, bandage", while "oris" is the genitive form of the Latin word "os", meaning "mouth". Therefore, "sphincter oris" translates to "tight binder of the mouth" or "mouth sphincter". This term refers to the circular muscle surrounding the opening of the mouth, also known as the orbicularis oris muscle, which plays a role in speech, chewing, and facial expressions.
