Question

Quizplus · Accepted Answer

Activation of a motor neuron during the processing of a reflex action carries the nerve impulse to the peripheral effector organs in order to produce a response. It is not instantaneous (A), and it does not typically enhance the original stimulus (C). The response is sent through the ventral root, not the dorsal root (D). Therefore, the correct answer is B.
