The two-point threshold varies for different parts of the body.

Question

Quizplus · Accepted Answer

The two-point threshold is the minimum distance at which two points of stimulation can be perceived as separate. It varies for different parts of the body due to the differences in the density of sensory receptors in each area. For example, the fingertips have a smaller two-point threshold than the back of the hand because there are more sensory receptors in the fingertips.
