GROSS ANATOMY

Detailed explanation-1: -The ventral rootlets from discrete spinal cord section unite and form the ventral root, which contain motor nerve axons from motor and visceral motor neurons.

Detailed explanation-2: -The ventral root of the spinal nerve contains the motor fibers of anterior motor neurons in the ventral horn, which pass to the skeletal muscles.

Detailed explanation-3: -The ventral roots consist predominantly of efferent somatic motor fibers (thick axons of alpha motor neurons and medium-sized axons of gamma motor neurons).

Detailed explanation-4: -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.
