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.

Origin

The depressor supercilii muscle originates from the lateral aspect of the nasal bridge - medial part of the orbital rim and fascia covering the lower part of the nasal bone.

 

Insertion

The depressor supercilii inserts on the medial side of the bony orbit in the skin below the eyebrow and intercanthal region.

The depressor supercilii muscle is innervated by the temporal branch of the facial nerve (CN VII).

 

Blood supply

The depressor supercilii is primarily supplied by the branches of the facial artery.
