BIOPHYSICAL AGENTS EXAM 1, 2

Mechanical traction has been surmised to provide which of the following effects? a. decreases discal fluid exchange and nutrient transport b. increased foraminal size c. micro shearing affects d. increase collagen tissue extensibility - Answer- b. increased foraminal size ___________ a. it actually increases it c and d. nonthermal US effects KAHOOT Which of the following is NOT true about pain? a. nociceptors become more sensitive to activation with peripheral sensitization. b. A-delta fibers respond to high intensity mechanical and thermal stimuli c. Sensation from C-fibers are often described as sharp and prickling. d. The gate control theory explains how large fibers block pain transmission to the brain. - Answer- c. Sensation from C-fibers are often described as sharp and prickling. C fiber sensations are dull, aching, and burning. Which of the following is NOT true about pain? a. C fibers respond to a broad range of stimuli b. When there is tissue damage, nociceptors send signals through the PNS through the spinal cord and then to the brain. c. Patients with chronic pain often exhibit psychosocial behaviors like depression d. High threshold neurons receive input from both nociceptive and non-nociceptive primary afferent fibers - Answer- d. High threshold neurons receive input from both nociceptive and non-nociceptive primary afferent fibers High threshold neurons receive info from the nociceptors only. Which of the following is NOT true about pain? a. Electrical stimulation and superficial heat are some modalities that stimulate A-beta fibers b. Chronic pain is often associated with increased muscle tone. c. A fibers conduct signals quickly, generating a withdrawal response d. W
