The Depressor Supercilii is an eye muscle of the human body. The nature of this muscle is in some dispute. Few printed anatomies include it (Netter, et al. ) and many authorities consider it to be part of the orbicularis oculi muscle . On the other hand, many dermatologists, ophthalmologists and plastic surgeons hold that the depressor supercilli is a distinct muscle and has a definite, individual effect on the movement of the eybrow and skin of the glabella.
