What is another term for the palpebral reflex?

• A. Eyelid reflex
• B. Toe pinch
• C. Cough reflex
• D. Tail pinch

Answer: (A)

The palpebral reflex is the blink response produced when the eyelids are gently touched or tapped. Saying it is an eyelid reflex is the simplest, exact way to describe the same phenomenon—it's the eyelid’s automatic closing in response to stimulation. This reflex helps assess neural pathways, involving sensory input via the trigeminal nerve and motor output via the facial nerve to the orbicularis oculi muscle. The other options describe different reflexes (toe or tail withdrawal, or coughing) and are not synonymous with blinking of the eyelids.
