Can you resum this while connecting it with Pathophysiology and explain why is relevant. RESUM: The foregoing review attests to the multidimensionality of pain. Pain is a biopsychosocial experience that goes well beyond mere nociception. In this regard, identification of the physical pathology at the site of injury is necessary but not sufficient to explicate the complex process by which somatosensory information is transformed into the physiological, cognitive, affective, and behavioral response labeled as pain. Indeed, in the case of chronic low back pain, the magnitude of tissue damage may be out of proportion to the reported pain experience, there may be no remaining structural impairment, and physical signs that have a predominantly nonorganic basis are likely to be present. In this and other chronic conditions, to consider such pain as malingering or somatization would be to grossly oversimplify the matter. Pain, whether linked with injured tissue, inflammation, or functional…

A 15-year-old girl complains of stress headaches. For the last few years, about one time a week, she develops a mild left-sided neck tightness that, after several hours, can spread to the left temporal area with moderate intensity and of a pounding quality. There is light and noise sensitivity and, sometimes, nausea. The headaches last about 8 hours and are minimally reduced by ibuprofen or sleep. The headaches often occur in the late afternoon as she comes home from school.   a migraine   b tension-type headache   c brain tumor headache   d temporal arteritis

True or false: a patient with damage to their left motor cortex will have trouble moving the left half of their body. True or false: hemiplegia most often results from damage to the brain. True or false: most medications and toxins injected into the bloodstream readily make their way into the cerebrospinal fluid.

The central nervous system serves as the communication center of our bodies. Explain how your hand touches something cold and you know it; refer to a sensory neuron and the correct lobe of the cerebrum.
