Question

Quizplus · Accepted Answer

The two major types of sensory receptors are exteroceptors (sensitive to external stimuli, such as touch, temperature, and pressure) and interoceptors (sensitive to internal stimuli, such as changes in blood pressure and blood pH). Chemoreceptors, mechanoreceptors, photoreceptors, thermoreceptors, and peripheral nervous system receptors fall under the categories of either exteroceptors or interoceptors. Therefore, choice E is the best answer.
