Detailed explanation-1: -The correct answer is (A) ventral roots. The ventral roots consist of motor neurons that carry impulses from the spinal cord to the extremities of the body. (B) dorsal roots are incorrect because they transmit sensory impulses from the rest of the body to the central nervous system.
Detailed explanation-2: -Neurons carry messages from the brain via the spinal cord. The neurons that carry these messages to the muscles are called motor neurons.
Detailed explanation-3: -The Ventral Root of the spinal nerve contains outgoing, efferent (meaning to “bear away from") fibers that carry information destined to control motor or glandular function. The cell bodies of these motor neurons are located in the ventral horns of the spinal cord’s central grey region.
