Hint: Pacinian corpuscles are found deep in the dermis of both glabrous and hairy skin. They are anatomically comparable to Meissner’s corpuscles and are found in the periosteum of the bone, joint capsules, pancreas and other viscera, breast, and genitals.

Complete solution
Option A. Pain: Pain receptors are referred to as “Nociceptors,” which are free nerve endings found everywhere in the body, including the skin, muscles, joints, bones, and internal organs. They play a crucial role in how the body feels and reacts to pain. The primary motive of a nociceptor is to react to damage to the body through signal transmission to the spinal cord and brain.
Option B. Pressure: Pacinian corpuscles are quickly adjusting mechanoreceptors that sense in depth transient (but not prolonged) pressure and high-frequency vibration. These receptors recognize pressure and vibration by being compressed, stimulating their internal dendrites
Option C. Movement: Proprioceptors are responsible to report every aspect of the movement to the central nervous system. These receptors are sensitive to position, posture, equilibrium and internal conditions of the body. Those proprioceptors that regularly check the position of limbs are the muscle spindles and tendon organs.
Option D. Temperature: Thermoreceptors help to detect temperature changes. These receptors comprise of Krause end bulbs, which help to detect cold and are determined by capsules; Ruffini endings, which help to detect warmth and are defined by extended endings of the dendrite; and warm and cold receptors found on free nerve endings that can detect an array of temperature.

Answer. Option B is correct

In human skin, four main tactile mechanoreceptors are present. It includes Merkel’s disks, Meissner’s corpuscles, Ruffini endings, and Pacinian corpuscles; two amongst them are located toward the surface and two are located deeper in the skin. A fifth kind of mechanoreceptor, Krause end bulbs, are present only in specialized areas.
