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 ^[1]. On the other hand, many dermatologists, opthamologists 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^[1].

Origin and insertion

The depressor supercilli originates on the medial orbital rim, near the lacrimal bone, and inserts on the medial aspect of the bony orbit, inferior to the corrugator supercilii. In some specimens it exhibits two heads and in others, only one.
