Match the following: 12) Preganglionic sympathetic. 13) Preganglionic parasympathetic. 14) Postganglionic sympathetic to sweat glands. 15) Postganglionic parasympathetic. 16) Most postganglionic sympathetic. A) Norepinephrine (NE) B) Acetylcholine (ACh) 12) 13) 14) 15) 16) TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false. 17) Because the ANS is a visceral motor system, afferent pathways are of no importance and actually are rarely found. 17) 18) The rami communicantes are associated only with the sympathetic division of the ANS. 18) 19) The gray rami communicantes consist of myelinated postganglionic fibers. 19) 20) Splanchnic nerves are mixed motor and sensory nerves. 20) 21) The autonomic nervous system may cause activation or inhibition, depending on the division that is active and the target that is affected. 21) 22) The celiac ganglion is primarily associated with the sympathetic division. 22) 23) The sympathetic chain is composed of collateral ganglia. 23) 24) Thermoregulatory responses to increased heat are mediated by the sympathetic nervous division. 24) 25) Most disorders of the autonomic nervous system reflect abnormalities of smooth muscle control. 25) 26) Alpha - adrenergic effects are usually stimulatory and mediatory. 26) 27) The adrenal medulla is considered a "misplaced" sympathetic ganglion by some. 27) 28) Acetylcholine is the substance released by the axonal endings of the somatic efferent fibers and by the parasympathetic nerve fiber endings. 28) 29) Most body organs are innervated by only the sympathetic division of the nervous system. 29) 30) Through direct neural stimulation, the sympathetic division promotes many metabolic effects via hormone release. 30) 31) Cranial nerves VII, IX, and X contain postganglionic fibers of the parasympathetic nervous system. 31) 2

32) The ANS stimulates smooth and skeletal muscles and glands, whereas the somatic nervous system innervates cardiac muscles only. 32) 33) Norepinephrine - releasing fibers are called cholinergic fibers. 33) 34) Autonomic ganglia are motor ganglia only. 34) 35) The craniosacral division is another name for the parasympathetic division. 35) 36) The chain ganglion, like the dorsal root ganglion, contains soma from sensory neurons. 36) 37) Most blood vessels are innervated by the sympathetic division alone. 37)
