Document Summary
Pain, temperature, and sleep neurology content 1. Describe the function and action of endogenous opioids (morphinelike neuropeptides: function= bind with opioid receptors to inhibit pain impulses in periphery, spinal cord, and brain. Responsible for sensations of well-being and modulation of many physical. Enkephalins most prevalent of the natural opioids & bind with delta receptors. Endorphins produces the greatest sense of exhilaration & natural pain relief. Dynorphins most potent of the endogenous opioids; bind with kappa receptors to impede pain signals. Endomorphins bind with mu receptors & have potent analgesic effects. Differentiate between acute and chronic pain: acute pain, protective mechanism. Alerts an individual to a condition or experience that is immediately harmful to the body: transient. Lasting seconds to days, sometimes up to 3 months: begins suddenly and relieved after pain stimulus removed, physical manifestations. Increased heart rate, hypertension, diaphoresis, dilated pupils: acute somatic. A-delta fibers: pain is sharp and well localized.
