vibration receptor

vibration receptor

a nerve ending that responds to various ranges of vibration frequencies. Vibration receptors have been identified through histological studies as Pacinian corpuscles, located at depths ranging from the skin surface to the connective tissue covering the surface of a bone. Some vibration receptors seem most sensitive to vibrations between 100 and 500 Hz, whereas others are most sensitive to those below 100 Hz.
