The depressor supercilii muscle is located near the eye, and it is thought to assist in moving and lowering the eyebrow. Also, it is thought to assist in moving the glabella, which is the skin above the nose and between the eyebrows.
This muscle originates near the tear ducts and extends to the middle of the eyebrow. The facial nerve supplies the depressor supercilii.
In comparison to other muscles of the face, it is relatively small. However, among physicians and researchers, there is still debate over whether the depressor supercilii is part of the orbicularis oculi. Some plastic surgeons believe the muscle to be independent with its own specific function, while other physicians argue that this muscle is actually a segment of the orbicularis oculi muscle.
