What type of sensory information is detected by the Pacinian corpuscle?

The Pacinian corpuscle, also known as a lamellar corpuscle, is specialized for detecting deep pressure and vibration in the skin and other tissues. These structures are found in the deeper layers of the skin and are particularly sensitive to changes in pressure and rapid vibration. When pressure is applied to the skin, the Pacinian corpuscles respond by generating nerve impulses that are transmitted to the central nervous system, signaling the presence of pressure.

Its specific adaptation to respond to pressure, rather than other sensory modalities like temperature, pain, or light touch, allows the Pacinian corpuscle to play a crucial role in helping the body perceive changes in its environment. This distinct function differentiates it from other receptors that are more attuned to detecting temperature (thermoreceptors), pain (nociceptors), or light touch (Meissner's corpuscles).
