Skin mapping indicates that
A) the forearm is the most sensitive area of the body.
B) skin receptors are found in varying concentrations, reflecting the sensitivity of the body areas.
C) pain receptors do not vary in concentration, but are uniform for all parts of the body.
D) all of these statements are true.

Question

Quizplus · Accepted Answer

Skin mapping has shown that skin receptors, such as touch, heat, and pain receptors, are not evenly distributed throughout the body. Some areas have a higher concentration of receptors, making them more sensitive to stimuli. The forearm is not necessarily the most sensitive area, as this can vary from person to person. Pain receptors can also vary in concentration, contrary to statement C. Therefore, statement B is the best choice as it reflects the findings of skin mapping research.
