Question

Quizplus · Accepted Answer

Somatic neurons are responsible for voluntary muscle movements, such as moving one's hand away from a sharp object. Therefore, if an individual is unable to pull their hand away from the object, it is likely due to a dysfunction or damage to their somatic neurons. The other options (sensory, sympathetic, and parasympathetic neurons) are not directly involved in voluntary muscle movements.
