The main purpose of a nociceptor is to respond to damage to the body by transmitting signals to the spinal cord and brain. There are two types of nociceptor: A delta fibres: activated by high threshold mechanoreceptors. thinly myelinated. Unmyelinated C-fibres: activated by polymodal nociceptors(PMN) and respond to intense mechanical stimulation, high temperatures and irritant chemicals.
Answer:
The correct answer would be D. species.
Natural taxon refers to the group of organisms which exists in nature as a consequence of evolution.
