Destruction of the anterior horn cell of the spinal cord would result in loss of:

  1. voluntary motor impulses
  2. commissural impulses
  3. integrating impulses
  4. sensory impulses

Correct answer: voluntary motor impulses

Solution

The anterior horn of the spinal cord contains lower motor neurons whose axons exit to innervate skeletal muscle. If these cells are destroyed, voluntary motor impulses cannot reach the muscles, causing flaccid weakness or paralysis.
