Which of the following stimuli will NOT activate a nociceptor?
A)extremes in temperature
B)very intense mechanical stimulation
C)specific chemicals in the extracellular fluid
D)chemicals released by injured cells
E)external odorant molecules

Question

Quizplus · Accepted Answer

Nociceptors are sensory receptors that detect potentially harmful stimuli, such as extremes in temperature, very intense mechanical stimulation, specific chemicals in the extracellular fluid, and chemicals released by injured cells. However, they do not detect external odorant molecules, which are detected by olfactory receptors in the nose. Therefore, the correct answer is E.
