What do heat receptors in the skin do first at the beginning of a reflex response?
Answer and explanation
Correct answer: They detect the heat stimulus and initiate a nerve signal
A reflex response begins when a receptor detects a potentially harmful stimulus. Heat receptors in the skin sense an unusually high temperature and convert that information into a nerve impulse. The impulse then travels through a sensory neuron toward the central nervous system, allowing a rapid response. Thus option A describes the first step; the other choices refer to unrelated functions of digestion, endocrine activity, or plants.
