The term is used when pain is perceived as originating at the surface of the body instead of the visceral organ from which the pain is actually originating. This comes pain fibers from th cutancous pain via the about because e visceral organ synapse on secondary neurons in the spinal cord that transmit a. referred pain; visceromotor system b. referred pain; anterolateral system c second pain; anterolateral system d. referred pain; corticospinal system e. second pain; visceromotor system 22. Increased sensitivity to painful stimuli near the site of an injury is referred to as a. allodynia b. hypoalgesia c. hyperalgesia d. hyperdynia e. analgesia 23. Non-steroidal anti-inflammatory drugs (NSAIDs) act to reduce pain by which mechanism? a. Block the enzymes that produce prostagladins b. Block the enzymes that produce Substance P c. Promote the release of bradykinins and histamines d. Activate the enzymes that break down enkephalin 24. With each succeeding stage of sleep (from I to 3): a. Breathing and heart rate increase b. Brain activity increases c. Low frequency, high-amplitude waves increase in number d. High frequency, low-amplitude waves increase in numberExplanation / Answer
20)a) heat (TRP channels also respond to heat)
21)b refered pain, anterolateral system (carries cutaneous pain)
22)c) hyperalgesia (increased sensitivity to pain)
23)a)block the enzymes that produces prostaglandin (cyclooxygenase enzymes) prostaglandins causes pain sensation.
24) c )low frequency , high amplitude waves increase in number.
