Question

Quizplus · Accepted Answer

Meissner corpuscles and Merkel disks are both types of receptors in the skin that detect fine touch. Pacinian corpuscles, Ruffini endings, and Krause end bulbs are other types of receptors that detect pressure, stretching, and cold respectively. Temperature receptors are indeed free nerve endings, but they are found in both the dermis and epidermis, not just in the dermis. Thus, the best choice is B.
