Question: 1 / 495

Which corpuscle in the skin is sensitive to cold?

Pacinian

Krause

Krause corpuscles are specialized nerve endings found in the skin and mucous membranes that respond specifically to cold temperatures. Their structure allows them to detect changes in temperature, especially in the cooler range, making them essential for thermoreception. When exposed to cold stimuli, Krause corpuscles become activated and send signals through peripheral nerves to the brain, which interprets these signals as the sensation of cold.

Understanding skin thermoreceptors is essential for practitioners in fields such as laser technology and dermatology, as body temperature regulation and sensory perception can significantly affect treatment outcomes and patient comfort. By recognizing the role of Krause corpuscles, professionals can better understand the physiological responses that may occur during various procedures, including those that involve thermal effects, such as laser treatments.
