Depressor supercilii muscle
Updates to Article Attributes
The depressor supercilii is a facial muscle located in the eye region between both eyebrows and orbits.
Terminology
The nature of this muscle is in some dispute as some anatomical specialists consider it to be part of the orbicularis oculi muscle, while others maintain that it is a distinct muscle.
Summary
origin: medial part of orbital rim, fascia covering lower part of nasal bone
insertion: skin below eyebrow and intercanthal region, medial side of orbit
blood supply: branches of the facial artery
innervation: temporal branch of facial nerve (CN VII)
action: depresses eyebrow
Gross anatomy
Origin
Thedepressor 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.
Arterial supply
The depressor supercilii is primarily supplied by the branches of the facial artery.
Innervation
The depressor supercilii muscle is innervated by the temporal branch of the facial nerve (CN VII).
Action
The main action provided by the depressor supercilii muscleis the depression of the eyebrow.
