Depressor Supercilii muscle

The Depressor Supercilii is a muscle of the eye in the human body. While many authoritative figures consider this muscle to be part of the orbicularis oculi, most dermatologists, ophthalmologists and plastic surgeons hold that it is a distinct muscle and has a definite, individual effect on the movement of the eyebrow and skin of the glabella.

The depressor supercilii 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.
