Question

Quizplus · Accepted Answer

Nociceptors are sensory receptors that respond to damaging or potentially damaging stimuli, such as high temperatures, and send signals to the brain that are interpreted as pain. In this case, the hot coffee causes tissue damage, which activates nociceptors and results in the perception of pain. Mechanoreceptors detect mechanical stimuli (such as touch or pressure), thermoreceptors respond to changes in temperature, and chemoreceptors respond to changes in chemical concentrations. While these receptor types may also be active during a coffee spill, they are not responsible for the sensation of pain.
