CIP (Congenital Insensitivity to Pain with Anhidrosis) is a rare genetic condition characterized by the inability to feel pain and temperature, as well as a reduced ability to sweat. The specific sensory receptors affected in this condition include:
- Thermal receptors (which detect temperature changes)
- Nociceptors (which detect pain stimuli)
Given the options you've provided, the most accurate choice would be:
A. Thermal receptors and mechanical receptors.
However, it's important to note that nociceptors, which are specifically responsible for detecting pain, are not mentioned in your choices. If you were to prioritize, focusing on thermal receptors (for temperature sensation) and acknowledging that mechanical receptors are responsible for detecting touch, pressure, and proprioception, choice A makes the most sense in the context of your question.
