Which muscle runs down the midline of the nose between the eyebrows and wrinkles the bridge of the nose?

Explanation:
The muscle that runs down the midline of the nose between the eyebrows and wrinkles the bridge of the nose is the procerus. It lies along the nasal bone and inserts into the skin between the eyebrows, so when it contracts it pulls that skin downward and medially, creating horizontal lines across the bridge of the nose and contributing to a frown. This distinguishes it from the other muscles listed: the nasalis mainly controls the nostrils (flaring or narrowing), the levator labii superioris lifts the upper lip, and the depressor anguli oris pulls down the corners of the mouth.
