What is the role of the Pacinian corpuscles in human skin?

Any deformation in the corpuscle leads to opening of pressure-sensitive or stretch-activated ion channels or mechanosensitive channels present in the axon membrane or axolemma of the neurite inside the core of the corpuscles or end-organ. This initiates generation of the receptor potential inside the corpuscles which is also secondarily supported by the voltage-activated ion channels present in the core of the corpuscles. Finally the receptor potential is modulated to neural spikes or action potential with the help of opening of sodium ion channels present at the first Ranvier's Node of the axon.
