Testing two-point discrimination location two-point discrimination(mm) anterior forearm 3 mm anterior thigh 7 mm face 6 mm vertebral region 39 mm fingertip 4 mm what results did you expect for each test? explain. did your observations agree with your expectations? interpret your results.

Two-point discrimination is the minimal distance which someone can perceive two different stimuli that given simultaneously. An area with higher receptor density will have a lower two-point discrimination result since the distance between receptor is lower. 
The area that needs a high sensitivity like the palm of the hands(especially the fingertips), face, and tongue should be the one with lowest two-point discrimination.

In this report, anterior forearm two-point discrimination result is the lower than the fingertip. This result is suspicious since the forearm shouldn't more sensitive than the fingertip. Fingertip two-point discrimination is around 2-6mm and forearm should be much higher than 6mm.

The answer is b) gene
