Question

Quizplus · Accepted Answer

The automatic reaction of blinking in response to wind is a function of the lower part of the brain, specifically the brainstem and the reflex arc. The adrenal hormones and frontal lobes are not directly involved in this reflex, and the spinal cord is only involved in transmitting the sensory information to the brain.
