Which three collateral ganglia serve as origins for ganglionic neurons that innervate organs or tissues in the abdominopelvic region?

What two distinctive results are produced by the stimulation of sympathetic ganglionic neurons?

Which six plexuses in the thoracic and abdominopelvic cavities innervate visceral organs, and what are the effects of sympathetic versus parasympathetic stimulation?

Dual innervation refers to situations in which (a) vital organs receive instructions from both sympathetic and parasympathetic fibers, (b) the atria and ventricles of the heart receive autonomic stimulation from the same nerves, (c) sympathetic and parasympathetic fibers have similar effects, (d) all of these are correct.
