Which of these is an example of an organ of the cholinergic type? a sweat gland A certain drug decreases heart rate by blocking a receptor on cardiac pacemaker cells. 1 and 3 Most sympathetic effector junctions release norepinephrine but a significant number release acetylcholine instead. the breakdown of triglycerides within adipocytes. The stimulation of beta-adrenergic receptors can lead toģ. Which of the following statements is true? Regarding the sympathetic nervous system, the neurotransmitter ACh is always excitatory when used in the synapses of the sympathetic nervous system. Stimulation of the beta receptors on heart muscle cells results in increased heart rate and force of contraction. Which of the following would you not expect to observe in a person who has taken a sympathomimetic drug? decreased blood pressure Sympathetic axon terminals form a branching network of swollen segments called varicosities. collateral The _ nervous system stimulates the arrector pili muscles and gives you "goosebumps." sympathetic Identify the structure labeled "6." ganglionic neuron Drugs that have effects similar to those of sympathetic activation are called sympathomimetic drugs. The celiac, superior mesenteric and inferior mesenteric ganglia are collectively called _ ganglia. Autonomic disorders would not cause problems related to skeletal muscle function. Each of the following effects is associated with the action of postganglionic sympathetic fibers except decreased heart rate. Postganglionic fibers that innervate targets in the body wall or thoracic cavity originate on neurons within sympathetic chain ganglia. Specialized ganglionic sympathetic neurons that release hormones into the bloodstream are found within the adrenal medullae. Which of the following is not innervated by the celiac ganglia? bladder The adrenal medullae secrete both epinephrine and norepinephrine. Preganglionic fibers that innervate the collateral ganglia form the splanchnic nerves. Collateral ganglia contain neurons that innervate tissues and organs in which cavity? abdominopelvic Sympathetic nerves contains short preganglionic fibers and longer postganglionic fibers. Stimulation of the neurons in the celiac ganglion would lead to conversion of liver glycogen reserves into glucose. Postganglionic axons usually are unmyelinated. collateral Injury to the neurons of a collateral ganglion would affect the function of the digestive tract. chain Clusters of ganglionic sympathetic neurons that innervate organs in the abdominopelvic region are called _ ganglia. Clusters of ganglionic sympathetic neurons lying along either side of the spinal cord are called sympathetic _ ganglia. short myelinated In the sympathetic nervous system, where are the preganglionic neurons located? thoracic and lumbar segments of the spinal cord Preganglionic neurons of the sympathetic nervous system are located in the lateral gray horns of segments T1 to L2 of the spinal cord. Sympathetic preganglionic fibers are _ and have _ axons.
