Detailed explanation-1: -The ventral horns contains the cell bodies of motor neurons that send axons via the ventral roots of the spinal nerves to terminate on striated muscles.
Detailed explanation-2: -The anterior root, also known as the ventral root, is a neural structure that stems directly from the spinal cord by the ventral horn of gray matter. This structure only contains motor neurons, however, it soon merges with the posterior (dorsal) root to form a spinal nerve that has motor and sensory 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.
