Predict what might happen if nociceptors were rapidly adapting instead of slowly adapting receptors. Would this change be beneficial or potentially harmful?

Hi, everybody. Welcome back. Here's our next problem. We have two statements here. First one says statement one, no se acceptors are mainly involved in pain sensitivity and synapse directly to the brain. Statement, two no receptors are not found in the brain. And then the problem says, choose which statements or statement or statements above is or are correct about noo acceptors. A one only B two only C, both one and two or D none of the above. So we just have to look at these two statements and see if they are true. So number one, part one, no receptors are mainly involved in pain sensitivity. They are the pain receptors. But then part two says synapse directly to the brain. So this part is incorrect. No se seor synapse first with the spinal cord or to the spinal cord before the signals are sent on to the medulla and midbrain. Or there's higher level processing of the intensity and localization of these pain signals, but they don't snap directly to the brain, they travel through the spinal cord first. So choice statement, one is incorrect. So we'll cross out choice A one only and then C both one and two. Now get the statement too. No su acceptors are not found in the brain. This is correct. The brain itself has no pain receptors, which is why people can have their brain operated on without anesthesia to the brain itself. There are no receptors found widely in skin muscles, joints, bone and viscera, all those places where you can feel aches and pains. And of course, if you're, for instance, having brain surgery, the structures around the brain itself, the skin, the bone can have sense pain, but the brain itself does not have no su acceptors. So statement two is correct. So we'll cross out choice D none of the above and our answer will be choice B two only. So the statements that are correct about noso acceptors is just choice B statement two only. See you in the next video.
