What is a krause end bulb?

A Krause end bulb is a type of sensory receptor found in the skin and mucous membranes, specifically associated with the sensation of cold. These specialized nerve endings are encapsulated and are sensitive to low temperatures, playing a role in thermoreception. They are named after the German anatomist Wilhelm Krause, who first described them. Krause end bulbs contribute to the body's ability to detect changes in temperature and maintain homeostasis.
