Final answer:
The nervous system likely contributed to his problems through impaired motor function.
Step-by-step explanation:
His nervous system likely contributed to his problems through impaired motor function. The nervous system controls movement through the coordination of brain signals and muscle actions. When the nervous system is damaged, it can result in difficulties with motor control and movement. For example, if the nerves that control muscle movement are damaged, it can lead to weakness, paralysis, or impaired coordination.
