Educational content only — not medical advice.
Anatomy
The eyebrow is an arched dermal ridge covered by short, stiff oblique hairs overlying the superciliary arch of the frontal bone. Acting as an essential facial landmark, it diverts sweat, rain, and debris away from the eye, enhances facial expression, and aids in nonverbal social communication.
Clinical notes
Madarosis (loss of eyebrow hair, especially the outer third / Queen Anne sign) is a classic clinical indicator of hypothyroidism or lepromatous leprosy.
