front 11 Identify if below is Sympathetic or Parasympathetic Increases blood pressure | back 11 Sympathetic |
front 12 True or False Since the ANS is a visceral motor system, afferent pathways are of no importance and actually are rarely found. | back 12 False |
front 13 True or False The rami communicantes are associated only with the sympathetic division of the ANS. | back 13 True |
front 14 The gray rami communicantes consist of myelinated postganglionic fibers. | back 14 False |
front 15 True or False Splanchnic nerves are mixed motor and sensory nerves. | back 15 False |
front 16 True or False The autonomic nervous system may cause activation or inhibition, depending on the division that is active and the target that is affected. | back 16 True |
front 17 True or False The celiac ganglion is primarily associated with the sympathetic division. | back 17 True |
front 18 True or False The sympathetic chain is composed of collateral ganglia. | back 18 True |
front 19 True or False Thermoregulatory responses to increased heat are mediated by the sympathetic nervous division. | back 19 True |
front 20 True or False Most disorders of the autonomic nervous system reflect abnormalities of smooth muscle control. | back 20 True |
front 21 True or False Alpha-adrenergic effects are usually stimulatory and mediatory. | back 21 True |
front 22 True or False The adrenal medulla is considered a ʺmisplacedʺ sympathetic ganglion by some. | back 22 True |
front 23 True or False Acetylcholine is the substance released by the axonal endings of the somatic efferent fibers and by the parasympathetic nerve fiber endings. | back 23 True |
front 24 True or False Most body organs are innervated by only the sympathetic division of the nervous system. | back 24 False |
front 25 True or False Through direct neural stimulation, the sympathetic division promotes many metabolic effects via hormone release. | back 25 True |
front 26 True or False Cranial nerves VII, IX, and X contain postganglionic fibers of the parasympathetic nervous system. | back 26 False |
front 27 True or False In contrast to the parasympathetic division, the sympathetic division has numerous ganglionic neurons in the gray matter of the spinal cord. | back 27 False |
front 28 True or False Norepinephrine-releasing fibers are called cholinergic fibers. | back 28 False |
front 29 True or False The parasympathetic division is a branch of the somatic nervous system. | back 29 False |
front 30 True or False The craniosacral division is the same as the parasympathetic division. | back 30 True |
front 31 True or False The chain ganglion, like the dorsal root ganglion, contains soma from sensory neurons. | back 31 False |
front 32 True or False Most blood vessels are innervated by the sympathetic division alone. | back 32 True |
front 33 True or False The blood vessels of the skin are one of the few areas of the body where the vessels are innervated by both the sympathetic and parasympathetic divisions. | back 33 False |
front 34 True or False Events recorded in a lie detector examination are controlled by the sympathetic division. | back 34 True |
front 35 True or False All splanchnic nerves are sympathetic. | back 35 True |
front 36 True or False Splanchnic nerves pass through the abdominal aortic plexus. | back 36 True |
front 37 True or False The structures that specifically exhibit vasomotor tone are mostly under sympathetic control. | back 37 True |
front 38 True or False Since many of the same cardiac cells are innervated by both parasympathetic and sympathetic fibers, the influence of the two divisions on the heart is synergistic. | back 38 False |
front 39 True or False β-adrenergic receptors are the only receptors found on the heart. | back 39 False |
front 40 True or False Autonomic reflex centers occur in the spinal cord, medulla, and midbrain. | back 40 True |
