Answer

Mechanoreceptors are primarily embedded in the skin and relay information related to touch and pressure. Merkel’s discs are found in both hairy and bare skin and provide continuous information on anything in contact with it. Meissner’s corpuscles are found mostly in bare skin and perceive changes in what the skin is touching. Pacinian corpuscles lie deeper in the skin and perceive vibrating stimuli.
