Depressor supercilii

The depressor supercilii (Latin: musculus depressor supercilii) is a facial muscle located in the eye region between both eyebrows and orbits. Many anatomical specialists consider this muscle to be a part of the orbicularis oculi muscle, instead of being a separate muscle. The depressor supercilii muscle is classified as the orbital facial muscle.
