Question

what are the three senses of touch that we have not yet identified specific receptors for? warmth, cold, pain pressure, cold, pain pressure, warmth, cold

Explanation:

In the study of touch receptors, warmth, cold, and pain are the three senses of touch for which specific receptors have not yet been fully identified (or the identification is more complex compared to others like pressure which has more defined receptors). The other options include pressure which has more established receptor understanding, so the correct set is Warmth, Cold, Pain.

Answer:

Warmth, Cold, Pain
