Which corpuscle is sensitive to pressure in the skin?

The correct answer is Pacinian corpuscles. These specialized sensory receptors are located deep within the dermis of the skin and are primarily responsible for detecting deep pressure and high-frequency vibration. They have a unique onion-like structure that allows them to respond effectively to changes in pressure. When pressure is applied to the skin, it causes deformation of the Pacinian corpuscle, which then generates a nerve impulse that the brain interprets as the sensation of pressure.

In contrast, the other types of corpuscles serve different sensory functions. Krause end bulbs, for instance, are associated with the sensation of cold. Ruffini corpuscles are sensitive to skin stretch and help in detecting sustained pressure, while Meissner corpuscles respond primarily to light touch and changes in texture. Understanding these functions helps professionals in the field of electrology and dermatology to comprehend how different sensations are processed by the body, especially when considering treatments that may involve manipulation of skin sensitivity or texture.
