7.   you're examining a two-year-old dairy cow. you move your open palm toward the cow's eye, looking for a blink. what are you evaluating?

Menace reflex

Explanation:

The threat reflex refers to a sudden blink of the animal's eyes in response to a threatening gesture, such as moving the open palm toward the cow's eye. This reflex does not manifest itself in animals with considerable lesions in the contralateral segment of the cerebral cortex. So testing the animal's threat reflex means that the vet wants to notice some damage to the contralateral segment of the cerebral cortex.
