In congestive heart failure the cardiac output is decreased True 107. a. b. False Neurotransmitters released onto a visceral effector by postganglionic autonomic axons include(s) 108. a norepinephrine secreted by most sympathetic axons b. acetylcholine secreted by parasympathetic axons c. epinephrine secreted by a few sympathetic axons d. all of the above 109 The branc h of the autonomic nervous system that is normally in control is the a. sympathetic branch b. parasympathetic branch c. both parasympathetic and sympathetic d. neither parasympathetic nor sympathetic The branch of the autonomic nervous system that increases intestinal peristalsis is the a. sympathetic branch b. parasympathetic branch c. both parasympathetic and sympathetic d. neither parasympathetic nor sympathetic 110. 111. The branch of the autonomic nervous system that increases blood glucose levels is the a. sympathetic branch b. parasympathetic branch c. both parasympathetic and sympathetic d. neither parasympathetic nor sympathetic 112. The branch of the autonomic nervous sy stem that causes bronchial dilation and dry mouth is the a. sympathetic branch b. parasympathetic branch c. both parasympathetic and sympathetic d. neither parasympathetic nor sympathetic The branch of the autonomic nervous system that decreases cardiac output and constricts pupils of the eyes is the sympathetic branch parasympathetic branch both parasympathetic and sympathetic neither parasympathetic nor sympathetic 113. a. b. c. d.Explanation / Answer
107.
The given statement is true. During congestive heart failure, the overload on ventricle results in reduced force of contraction and the heart muscle contraction is not efficient due to the reduced cross linking of actin and myosin in over-stretched heart muscle fibers. The option a is correct.
108.
The autonomuc postganglionic fibers release the neurotransmitter called norepinephrine. The post ganglionic fibers are also known as adrenergic neurons. In postganglionic neurons the norepinephrine is synthesized and stored in synaptic vesicles and released by exocytosis. The option a is correct.
109.
Parasympathetic nervous system is division of autonomic nervous system that is involved in functions like rest and digestion and promotes calming of the nerves return to regular function. Therefore, option b is correct. The sympathetic division is involved in fight or flight responses and energy generating processes.
110.
Parasympathetic nervous system monitors the function of digestion and increases the blood flow in GI tract by dilating blood vessels and accelerates peristalsis, mediating digestion of food . The option b is correct.
