Ted is a war veteran who was hit in the back with small pieces of shrapnel. His skin is numb in the center of his buttocks and along the entire posterior side of a lower limb, but there is no motor problem. Indicate which of the following choices is the most likely site of his nerve injury, and explain your choice: (a) a few dorsal roots of the cauda equina, (b) spinal cord transection at C6, (c) spinal cord transection at L5, (d) femoral nerve transected in the lumbar region.
Select the best answer or answers from the choices given: Destruction of the ventral horn cells of the spinal cord results in loss of (a) integrating impulses, (b) sensory impulses, (c) voluntary motor impulses, (d) all of these.
Which of the following is NOT true in adults? (A) The tapering end of the spinal cord may terminate as high as T12 or as low as L3. (B) The first cervical nerves lack dorsal roots in 50% of people. (C) The coccygeal nerve may be absent. (D) The terminal filum is the vestigial rem- nant of the caudal part of the spinal cord that was in the tail of the embryo. (E) The spinal cord has a lumbar enlargement for the lower limb but no equivalent enlargement for the smaller upper limb.
