If a motor neuron in the body were stimulated by an electrode placed about midpoint along the length of the axon ________.
A) the impulse would move to the axon terminal only
B) muscle contraction would occur
C) the impulse would spread bidirectionally
D) the impulse would move to the axon terminal only, and the muscle contraction would occur
