The condition CIPA (Congenital Insensitivity to Pain with Anhidrosis) specifically affects the ability to sense pain and temperature. This means that the sensory receptors involved are:
- Thermoreceptors (which detect temperature changes),
- Nociceptors (a type of mechanoreceptor that detects pain).
Given the options provided, the best match would be thermoreceptors and mechanoreceptors, as mechanoreceptors also include nociceptive receptors involved in sensing pain.
So, the correct response is:
thermoreceptors and mechanoreceptors.
