Answer 1

Pruriceptive pruritus is itch originating from external stimuli on the skin, such as eczema. It is the result of signals from specialized nerve endings called free nerve endings.

Step-by-step explanation:

Pruriceptive pruritus refers to itch originating from external stimuli on the skin. It is the result of signals being sent from specialized nerve endings called free nerve endings, which are sensitive to painful stimuli, hot and cold, and light touch. These nerve endings are slow to adjust to a stimulus and are less sensitive to abrupt changes in stimulation. An example of pruriceptive pruritus is itchiness caused by eczema, an allergic reaction that leads to dry, itchy patches of skin.
