Which of the following correctly describes receptors in the skin?
A) Pacinian corpuscles, Ruffini endings, and Krause end bulbs detect pain.
B) Meissner corpuscles and Merkel disks detect fine touch.
C) One type of nerve cell detects both hot and cold.
D) All receptor types are spread uniformly throughout dermal tissue.
E) Temperature receptors are free nerve endings in the dermis.
Pacinian Corpuscles
Sensory receptors located deep in the skin and responsive to pressure and vibration.
Meissner Corpuscles
A type of tactile mechanoreceptor found in the glabrous (hairless) skin, responsible for sensitivity to light touch.
Krause End Bulbs
Sensory receptors located primarily in the mucous membranes and are known for their role in detecting cold sensations in humans.

Final Answer :
B
Explanation :
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.
