Final answer:

The two-point discrimination subtest measures the density of sensory endings and receptive fields in the skin. The fingertips have the highest sensitivity to fine touch, allowing for the detection of texture and shape. Failure to recognize two points may indicate a dorsal column pathway deficit.

Step-by-step explanation:

The two-point discrimination subtest is used to measure the density of sensory endings and receptive fields in the skin. The fingertips have the highest sensitivity to fine touch, allowing for the detection of texture and detailed shape of objects.

When testing two-point discrimination, the patient is asked to identify whether one or two stimuli are present while keeping their eyes closed. Failure to recognize two points may indicate a dorsal column pathway deficit.
