Final answer:
C fibers are responsible for transmitting dull or burning pain to the brain, playing a major role in chronic pain sensation. Hence option B is correct.
Step-by-step explanation:
The type of receptor cell responsible for transmitting dull or burning pain to the brain is the C fibers. Thus option B is correct.
These are unmyelinated nerve fibers that are involved in the transmission of chronic, lingering, and less localized pain sensations, in contrast to the faster A-delta fibers that transmit acute, well-localized pain sensations. When tissue is damaged or inflammation occurs, chemical messengers such as cytokines and prostaglandins are released, activating nociceptors (pain receptors) which are transmitted to the central nervous system via A and C fibers. The noxious stimuli and subsequent pain signals travel through various nociceptive pathways, eventually reaching the primary somatosensory cortex in the brain for the final processing of the pain perception.
