Where are pain receptors located in the human body?
No, the pain receptors are peripheral. You have somatic and visceral. The somatic receptors receive pain from the skin, muscles, fat, etc. The visceral receptors receive pain from your heart, vowels, vessica urinaria, etc. The cerebral cortex does not “feel” pain, only the layers that cover it, so once you’ve gone through them, it’s ok (that’s why you can have brain surgery with someone awake and local anesthesia for the layers of the brain) The nocioceptive receptor (receptor for pain stimuli) are the free endings of nerves, they do not have a structure that would sense them, it’s just the plain open end of a nerve (unlike mechanoreceptors, photoreceptors,etc.) The part of your brain that processes all the incoming information of pain (and others) is the Thalamus (via spinal cord) and the projections to the cerebral cortex (Parietal Lobe). You also have a control of pain in the Periacueductal Gray Matter, which releases opioids to control pain reception. There are other pathways to co
