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 with an enlarged nerve terminal. This is sometimes referred to as a Merkel cell–neurite complex, or a Merkel disc receptor. A single afferent nerve fibre branches to innervate up to 90 such endings.
