Question

1. what layer of the skin did you reach? (hint: you should have felt the pressure.)

a. epidermis
b. dermis
c. hypodermis
d. stratum corneum

1. what trial was the most sensitive?

a. the trial that required the largest distance to feel two points
b. the trial where only one point was felt
c. the trial where two points were felt at the smallest distance
d. the trial that measured temperature

1. which did your group feel the best, the one point or the two points?

a. neither, both felt the same
b. it depended on the day
c. two points in areas with high receptor density
d. one point everywhere

Explanation:

1. The dermis contains nerve endings that can sense pressure. The epidermis (A) is the outermost layer without pressure - sensing in the same way. The hypodermis (C) is mainly for fat storage. The stratum corneum (D) is part of the epidermis.
2. Sensitivity in a two - point discrimination test is determined by the ability to distinguish two points. A smaller distance required to feel two points indicates higher sensitivity.
3. In areas with high receptor density (e.g., fingertips), the ability to distinguish two points is better as there are more sensory receptors to pick up the stimuli.

Answer:

1. B. Dermis
2. C. The trial where two points were felt at the smallest distance
3. C. Two points in areas with high receptor density
