What is the Difference Between Merkel Cells and Meissner Corpuscles ...

Merkel nerve endings are mechanoreceptors, a type of sensory receptor, that are found in the basal epidermis and hair follicles. They are nerve endings and provide information on mechanical pressure, position, and deep static touch features, such as shapes and edges. Merkel cells in the basal epidermis of the skin store serotonin which they release to associated nerve endings in response to pressure. Each ending consists of a Merkel cell in close apposition … WebMerkel nerve endings are found in the basal layer of glabrous and hairy skin, in hair follicles, and in oral and anal mucosa. In humans, Merkel cells (along with Meissner's corpuscles) occur in the superficial skin layers, and are found clustered beneath the ridges of the fingertips that make up fingerprints.
