Introduction:
Spinal cord and brain are a part of the central nervous system (CNS). The spinal cord is divided into 31 sections, each of the sections are having a pair of dorsal and ventral roots; and dorsal root ganglia. When the motor neuron is activated, the action potential travels via the ventral root to the effector organs.
Explanation of Solution
The ventral root is also known as the anterior root. It is able to control the peripheral effectors via the visceral motor neurons. The ventral root consists of the axons of motor neurons. A dorsal and ventral root combines to give rise to the spinal nerve that goes through the intervertebral opening. The ventral roots are thinner than the dorsal roots.
Therefore, it can be concluded that the term ventral root can be correctly matched with option (d) motor neuron axons.
