Final answer:
Nociceptors are responsible for transmitting pain signals in the body, detecting harmful stimuli and facilitating the sensation of pain. Option B.
Step-by-step explanation:
Nociceptors, also known as pain receptors or fibers, play a crucial role in the body's ability to transmit pain signals. These receptors detect potentially damaging stimuli such as mechanical, chemical, or thermal stresses.
When tissues are stressed or damaged, they release chemicals that activate nociceptors, contributing to the sensation of pain.
An interesting example of how these receptors work involves capsaicin, the active ingredient in hot peppers, which binds to nociceptors and can be used as a topical analgesic due to its long-lasting binding properties that reduce other stimuli's ability to elicit pain through the activated nociceptor.
So Option B is correct.
