The Autonomic Nervous System - Part 3
The autonomic nervous system coordinates many bodily functions that are not generally under conscious control (i.e., involuntary functions). For example, the autonomic nervous system regulates the function of cardiac muscle, smooth muscle, and various glandular structures (e.g., sweat glands, salivary glands, and some endocrine glands). Test your basic knowledge of the autonomic nervous system by taking this simple quiz.
(1)   All of the following catecholamine molecules are released by chromaffin cells of the adrenal medulla. Rank the molecules according to the amount released.
(2)   Sympathetic ganglia are located closer to the central nervous system, whereas parasympathetic ganglia are located closer to the target tissues.
(3)   Parasympathetic ganglia are located closer to the central nervous system, whereas sympathetic ganglia are located closer to the target tissues.
(4)   Preganglionic sympathetic neurons stimulate these cells of the adrenal medulla to release messenger molecules into the bloodstream:



(5)   When catecholamines are released from chromaffin cells of the adrenal medulla, the following is/are also co-released from the very vesicles containing catecholamines.
