Pacinian corpuscles are rapidly adapting (phasic) receptors that detect gross pressure changes and vibrations in the skin. Any deformation in the corpuscle causes action potentials to be generated by opening pressure-sensitive sodium ion channels in the axon membrane. This allows sodium ions to flow into the cell, creating a receptor potential. These corpuscles are especially sensitive to vibrations, which they can sense even centimeters a… WebThe Pacinian corpuscle or Vater-Pacinian corpuscles or Lamellar corpuscles in the skin and fascia detect rapid vibrations of about 200–300 Hz.
