Which muscle is described as the continuation of the frontalis and travels down the midline of the nose between the eyebrows, wrinkling the bridge of the nose?

• A. Nasalis
• B. Levator Labii Muscle
• C. Procerus Muscle
• D. Depressor Anguli Oris

Answer: (C)

The muscle described is the procerus. It runs from the nasal bones up into the skin between the eyebrows, effectively continuing the path of the frontalis into the midline of the face. When it contracts, it pulls the skin between the eyebrows downward, producing the wrinkles across the bridge of the nose. This specific action distinguishes it from other facial muscles: the nasalis surrounds the nostrils, the levator labii superioris lifts the upper lip, and the depressor anguli oris pulls the mouth corners down.
