Merkel’s Corpuscles


Merkel’s disks, epithelial receptor cells in the deep layers of the epidermis of mammals, including man.

Merkel’s corpuscles are sensitive to tactile stimuli arising from skin contact with surrounding objects, transmitting them to the sensory cells of the spinal ganglia. The corpuscles were first described in 1875 by the German histologist F. Merkel. They were studied in detail by the Russian scientist A. S. Dogel’ in 1903. Merkel’s corpuscles are found in especially sensitive areas of the skin, such as the lips. The corpuscles are surrounded by extremely delicate sensory nerve endings.
