[aabwk4]

Brian, a 4-year-old boy, is demonstrating the Gower's sign, and his mother is wondering why her child is making this movement. The child is doing this because:
 
  1. The weakness of his arms requires his legs to do more work.
   2. The weakness in his hips and thighs requires help from his arms to stand.
   3. Weakening trunk and back muscles require the legs and arms to help keep an upright position.
   4. Weakening of the trunk requires this movement to help breath.

Question 2

Which type of pain is transmitted by C-nerve fibers? Select all that apply.
 
  a. diffuse and dull
  b. burning and chronic
  c. pain that comes and goes unexpectedly
  d. unremitting and unbearable pain
