The normal palpebral reflex results in the blinking of the eyelids when the area around the eyes is gently tapped or stimulated. This response indicates proper functioning of the trigeminal nerve (cranial nerve V), which mediates sensation, and the facial nerve (cranial nerve VII), which controls the muscles involved in blinking. A positive reflex suggests intact neurological pathways and is often assessed during neurological examinations. Absence of this reflex could indicate potential nerve damage or neurological issues.
