Detailed explanation-1: -Most axons in the ventral roots arise from motor neurons in the ventral horn of the spinal cord and innervate skeletal muscle.
Detailed explanation-2: -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-3: -In anatomy and neurology, the ventral root of spinal nerve, anterior root, or motor root is the efferent motor root of a spinal nerve. At its distal end, the ventral root joins with the dorsal root to form a mixed spinal nerve.
Detailed explanation-4: -The ventral roots consist predominantly of efferent somatic motor fibers (thick axons of alpha motor neurons and medium-sized axons of gamma motor neurons).
