Meissner's corpuscles are small, nodular structures which penetrate the nerve cells. They contain spiral nerve fibrils which innervate tissues throughout the body, including the epidermis of the hands, fingers, feet, and the mucous membranes of the eyelid and tongue. They are strongly related to the tactile senses. Research Meissner's Corpuscles
Merkel's disks are oval-shaped receptors arranged in bundles and located in the epidermis. They are concentrated in the fingertips and other areas where Meissner's corpuscles are found. It is believed that these disks inform the brain of continuous touch on an area of the skin. Research Merkel's Disks
