Question

Quizplus · Accepted Answer

Free nerve endings are the skin structure that are responsible for detecting pain. They are distributed throughout the skin and are sensitive to changes in temperature, pressure, and chemical stimuli. Krause's end bulbs, Merkel's disks, and Pacinian corpuscles are all skin receptors that are important for touch, pressure, and vibration perception, but they are not specialized for detecting pain.
