A thermoreceptor is a non-specialised sense receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range.

WebLamellar corpuscles, or Pacinian corpuscles or Golgi-Mazzoni corpuscles , are one of the four major types of mechanoreceptor. They are nerve endings in the skin responsible for sensitivity to vibration and pressure. Vibrational role may be used to detect surface, e.g., rough vs. smooth. WebA Pacinian corpuscle is an onion-shaped structure of nonneural (connective) tissue built up around the nerve ending that reduces the mechanical sensitivity of the nerve terminal itself. If the onionlike capsule is entirely removed, mechanical sensitivity not only remains but is somewhat greater than when the capsule is present.
