Which term refers to the Ring Muscle of the eye socket?

• A. Quadratus Labii Superiorosis
• B. Orbicularis Oculi
• C. Depressor Labii Inferioris
• D. Mentalis

Answer: (B)

The ring-shaped muscle around the eye socket is the orbicularis oculi. Its circular arrangement around the eyelids lets it close the eyes fully when you blink or wink, protecting the eye. It actually has two parts—the orbital portion that tightens around the eye and the palpebral portion that gently lids the eyes during blinking—both reflecting its surround-the-eye, ring-like character. The other muscles listed sit around the mouth or chin, not around the eye, so they don’t perform the surrounding-eye function.
