Question

what did you use this instrument to test?

a. taste
b. sight
c. hearing
d. touch

Explanation:

Identify the instrument shown

The image displays a caliper (specifically, an aesthetic plastic vernier caliper often used in physiology labs).

Determine the physiological test

In human anatomy and physiology labs, calipers are used to measure the distance between two points on the skin to perform the two-point discrimination test.

Relate test to sensory modalities

The two-point discrimination test evaluates tactile acuity and the density of Sensory Receptors in different regions of the skin.

Match with the given options

Since the test measures tactile acuity on the skin, it is used to test the sense of touch.

Select the correct option

The correct option corresponding to touch is option d.

Answer:

• a. taste
• b. sight
• c. hearing
• d. touch (Correct answer)
