WebSpecifically, the corpuscle is the nerve ending, or the tip of a very specialized peripheral … 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 …
