It is a triangular shaped muscle located within the glabella region of the face. Attachments – Originates from the medial aspect of the superciliary arch and inserts onto the skin of the eyebrow. Actions – Draws the eyebrows together, creating vertical wrinkles on the bridge of the nose (associated with frowning). Innervation – Temporal branches of the facial nerve. Blood supply – Branches of the ophthalmic and superficial temporal artery. By TeachMeSeries Ltd (2026) Fig 1The two orbital muscles of facial expression.
