Question

Quizplus · Accepted Answer

Nociceptors are sensory receptors that detect potentially damaging stimuli, such as heat, pressure, or chemicals. When these receptors are activated by a hurtful stimulus, they initiate neural impulses that are transmitted to the spinal cord and then to the brain, leading to the sensation of pain. Endorphins are natural painkillers released by the body that can help reduce pain perception, but they do not initiate the impulse. The semicircular canals are part of the inner ear and are responsible for sensing balance and equilibrium, while olfactory receptor cells detect odors in the air. Neither of these are involved in the sensation of pain.
