Orbicularis oris muscle. In human anatomy, the orbicularis oris muscle is a complex of muscles in the lips that encircles the mouth. Until recently, it was misinterpreted as a sphincter, or circular muscle, but it is actually composed of four independent quadrants that interlace and give only an appearance of circularity.
Swollen lips, or lip oedema, is when one or both lips enlarge or distend beyond their normal size. This swelling is caused by a build-up of fluid, or inflammation inside the lip tissue. It can have many causes, including injury, illness, certain medicines or allergies. Swollen lips can be a sign of anaphylaxis â a severe allergic reaction â which requires immediate medical attention. In less serious cases, swelling may appear and disappear quickly, for example after chapping or sunburn.
