1. Which would be more likely to have an individualized, specific effect in the body: the sympathetic system or the parasympathetic system?
A) the sympathetic, because it stimulates the skeletal muscles, causing rapid activation.
B) the sympathetic, because the ganglia are connected to each other.
C) the parasympathetic, because it directly stimulates the adrenal medulla, releasing large quantities of epinephrine into the systemic circulation.
D) the parasympathetic, because the postganglionic fibers are very short, ending at a specific effector organ.
