The branch of the autonomic nervous system that includes only adrenergic fibers a. sympathetic branch b. parasympathetic branch c. both parasympathetic and sympathetic d. neither parasympathetic nor sympathetic 116. The branch of the autonomic nervous system that is includes only cholinergic fibers a. sympathetic branch b. parasympathetic branch c. both parasympathetic and sympathetic d. neither parasympathetic nor sympathetic 117. The branch of the autonomic nervous system that emerges from the brain and the sacral spinal cord is the a. sympathetic branch b. parasympathetic branch both parasympathetic and sympathetic c. 118. All parasympathetic target organs a. have muscarinic receptors b. are stimulated by the neurotransmitter c. are controlled by both the somatic and autonomic branches of the nervous system d. have both alpha and beta receptors 119. Tricyclic antidepressants work by a. opening postsynaptic beta receptors b. increasing axonal release of serotonin c. inhibiting the degradation of norepinephrine by acetylcholinesterase d. prolonging the activity of norepinephrine on postsynaptic membranes The autonomic nervous system is most directly influenced by the a. hypothalmus b. cerebral cortex c. sacral spinal nerves d. cerebellum 120. Contraction of muscle requires a. calcium 121. b. cholinergic receptors on the motor end plate c. stimulation from a neuron d. all of the aboveExplanation / Answer
114. The Parasympathetic nervous system is where the ganglion is located close to the Visceral organs and supplies to it. So the answer is (B).
115. The symphathetic branch of ANS is excitatory in nature and consist only adrenergic nerve fibres. The answer is (A)
116.The Parasympathetic branch of ANS are inhibitory in function and consist only cholinergic fibres. The answer is (B).
117. The branch of nervous system that emerges from brain and sacral spinal cord is the symphathetic branch(A)
118. All parasympathetic organs are stimulated by neurotransmitters (B).
119. Tricyclic antidepressants work by increase the production of serotonin and norepinephrine thus decrease the depression. Answer is (B).
120. The ANS is most influence by Hypothalamus, the autonomic body situated in cranial cavity. Answer is A.
121. Contraction of muscle requires- calcium, cholinergic receptors, and neuronal firing. Answer is all the above (D).
