Document Summary

Psyc302: psychology of pain: pain anatomy: the big picture. 2: pain-relevant loci (for pain below the neck), skin/muscle/joint/viscera ( periphery , dorsal root ganglion (drg, dorsal horn of the spinal cord, brain, ascending pathways (the pain matrix , ventro-basal thalamus, si, sii. If it gets down to the muscle, joints, viscera. Muscle hurting while running telling you to stop before you do serious damage. Something in the brain: you"re dead anyways. Information gets back down from the brain and ends up going through the spinal cord: modulates pain, why dorsal, the basic layout of vertebrates. Dorsal: no real reasons behind why, skin anatomy. Free nerve ends that don"t have any specific capsules. 4: most of the information we have on pain is on this kind of skin, even though most of our body is hairy skin, a nociceptor, responds to noxious stimuli, nociceptors are unipolar neurons. Bipolar neurons are only found in the eyes and ears.
