Which two blink reflexes are caused by CN 2 stimulation?

The correct answer is based on understanding the origin and function of the blink reflexes associated with different sensory stimuli. The trigeminal nerve (CN V) primarily mediates the blinking response to tactile stimuli, while the optic nerve (CN II) is involved in certain visual stimuli that trigger blink reflexes.

The dazzle reflex is a response to bright light and is indeed mediated by the optic nerve. When intense light enters the eye, the optic nerve sends signals to the brain, which results in a protective blink reflex to shield the eyes from potential harm caused by overstimulation.

The menace reflex also involves the optic nerve. It is a blink response elicited when an object moves rapidly towards the eye, prompting a protective blink response as a defensive mechanism.

Both of these reflexes—dazzle and menace—demonstrate the role of CN II in processing visual information that necessitates a rapid protective response from the eyelids. Therefore, this choice correctly reflects the two blink reflexes associated with the stimulation of the optic nerve.
