Muscles
Looks like
A thin muscle along the side of the nose, from the upper jaw beside the nose bridge down to the nostril wing and the upper lip.
What it does
Lifts the upper lip and flares the nostril, as in a snarl or a deep breath through the nose.
Keeping it well
Powered by the facial nerve. Rarely a problem by itself; weakness shows as part of a facial palsy.
