Explanation / Answer

16) sympathetic preganglionic axons synapse in collateral ganglia. These axons synapse on sympathetic postganglionic neurons in sympathetic chain

18) The sympathetic stimulation of the postganglionic cells of the adrenal medulla cause the release of acetylcholine and epinephrine.

19) Vagus nerve carries parasympathetic impulses to the thorasic and abdominal viscera. It is the 10th cranial nerve. The vagus nerves are paired.

15) Parasympathetic neurons is responsible for rest and digest activities. They are autonomic or viscera
