What does the two-point discrimination test measure?

A) the distribution of nociceptors
B) the distribution of chemoreceptors on the skin
C) the distribution of touch receptors on the skin
D) the distribution of thermoreceptors on the skin

Two-Point Discrimination

The ability of the skin to distinguish two nearby points as separate stimuli, a measure of sensory nerve function.

Nociceptors

Sensory receptors that respond to potentially harmful stimuli by sending nerve signals to the brain triggering the sensation of pain.

Chemoreceptors

Sensory receptors that respond to chemical stimuli, such as those found in the nose, tongue, or certain body cells.
