Why is fingertip sensation enhanced compared with proximal parts of our bodies?
A. Because our fingers are more exposed to the environment
B. Because we need more sensation in our fingertips to prevent injury
C. Because fingertips have a higher density of receptors and smaller receptive fields
D. Because fingertips are glabrous
ANS: C
Superficial sensation is also referred to as cutaneous sensation. Compared with the proximal parts of our bodies, the distal parts have a higher density of receptors and smaller receptive fields. This arrangement contributes to enhanced fingertip sensation, such as the ability to distinguish be-tween one and two stimuli that are close together.
