Detailed explanation-1: -Answer and Explanation: If the ventral root of a spinal nerve was severely damaged or cut, it would cut off the pathway of motor information from the spinal cord to the spinal nerve. Therefore, whatever effectors that spinal nerve controlled would no longer work; it would be paralyzed.
Detailed explanation-2: -Ventral root avulsion is a proximal nerve root lesion in which ventral motor nerve rootlets are torn from surface of the spinal cord, resulting in extensive death of motoneurons.
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.
