Which of the following receptors is responsible for measuring the intensity of a steady pressure on the skin surface?
The Ruffini ending is a tonic receptor that produces a train of action potentials proportional to the intensity of pressure applied to the skin. The Pacinian corpuscle is a very rapidly adapting receptor that fires once or twice in response to skin deformation. It can produce a continuous train of action potentials if the stimulus is repetitively applied and withdrawn. Therefore, the Pacinian corpuscle is used to encode vibration.
Pacinian corpuscle
Ruffini ending
Merkel's disk
Meissner's corpuscle
