- Depressor supercilii muscle
Depressor supercilii Latin musculus depressor supercilii Origin Medial orbital rim Insertion Medial aspect of bony orbit Artery Nerve Facial nerve Actions Depression of eyebrow
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 supercilii is a distinct muscle and has a definite, individual effect on the movement of the eybrow and skin of the glabella.
Origin and insertion
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.
