Destruction of the anterior horn cells of the spinal cord would result in loss of
A
Commissural impulses
B
Integrating impulses
C
Sensory impulses
D
Voluntary motor impulses
Explanation: 

Detailed explanation-1: -The destruction of the anterior horn cells of the spinal cord would result in the loss of voluntary motor impulses because it is majorly related to the motor impulses.

Detailed explanation-2: -The large anterior horn cells, concerned with the innervation of skeletal muscle, exit through the anterior roots to the peripheral nerve. The nerve fibers conduct the nerve impulse with a velocity directly proportional to their diameter and the size of their myelin sheaths.

Detailed explanation-3: -Poliomyelitis, spinal muscular atrophy, amyotrophic lateral sclerosis and progressive muscular atrophy are diseases that frequently include problems within the anterior horn.

Detailed explanation-4: -one of the divisions of the grey matter of the spinal cord, the anterior horn contains cell bodies of alpha motor neurons, which innervate skeletal muscle to cause movement.
