Quizplus · Accepted Answer

According to the two-point discrimination test, areas with more sensory receptors will be more sensitive. The lips have a high density of sensory receptors, which makes them the most sensitive area of the body for this test. The back of the torso has the lowest sensitivity because there are fewer sensory receptors in that area. Calves of the legs and forearms fall in between. Therefore, the best choice is D) Lips.
