Muscle that lowers the nose (M. Depressor Glabellae, Jna)

The depressor bridge muscle is one of the muscles of the facial skeleton, responsible for the ability to close the eyes. This muscle fiber is part of the facial muscles that control the opening and closing of the eyes.

One of the most important aspects of this muscle is its ability to lower the front of the face. When the muscle contracts, it helps to narrow the eyes and lower the front of the forehead. The muscle is also responsible for raising the eyebrow and opening the eyeball.

The muscle fibers are located in the front of the forehead between the eyebrows and the bridge of the nose, extend down the cheekbone to the angle of the jaw and then deepen into the skin inside the palpebral fissure. A certain number of muscle fibers extend upward into the bridge of the nose, forming the posterior arm of the muscle that encircles the upper eyelid. The medial fascicles of the flexor anterior muscle raise the upper eyelid to the forehead and maxilla, and also form the levator magnus, while the lateral fascicles of the levator magnus limit upward movement of the skin in the ear and face. They make up about 3-4% of the total number of facial muscles and are innervated by the first nerve of the facial nerve.
