Depressor supercilii

The depressor supercilii (also depressor supercilii muscle, latin: musculus depressor supercilii) is a facial muscle located in the eye region.

However, many anatomical specialists consider it to be a part of the orbicularis oculi muscle, insted of being a separate muscle.

Origin

The depressor supercilii originates from the medial orbital rim, from the fascia covering the lower part of the nasal bone.

Insertion

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

Action

The main action provided by the depressor supercilii is the depression of the eyebrow.

Innervation

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

Blood supply

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