Musculus corrugator supercilii · Svraštovač obočí
Muscles
Looks like
A small narrow muscle under the inner half of each eyebrow, running from the bony brow ridge near the nose to the skin above the middle of the brow.
What it does
Pulls the eyebrows down and together, making the vertical frown lines between them; shields the eyes from glare.
Keeping it well
Powered by the facial nerve. Sudden drooping of one side of the face is a stroke until proven otherwise: call emergency services.
