The mechanoreceptors primarily responsible for feeling the vibrations from an electric toothbrush are rapid vibrations because these receptors contain an "onion-like" series of layers.
Perception of vibration sensations is carried out by two major types of mechanoreceptors, Meissner's corpuscles (MC) and Pacinian corpuscles (PC). MCs are large myelinated fibers that detect low-frequency vibrations and are present in the bald (smooth and hairless) skin of the fingertips and eyelids.
The skin has specialized sensory receptors called mechanoreceptors that allow it to sense different modes of touch. Pacinian corpuscles are located deep in the dermis of the skin and are responsible for sensing vibrations.
The major mechanoreceptors, Pacinian corpuscles, and Ruffini endings are located in the underlying layer and respond to deeper touch.
