Both branches of the autonomic nervous system innervate most organs with opposite functions: one to maintain rest and the other to increase activity.ĭ. There are two somatic neurons going to each muscle so that a muscle can still function if one neuron is damaged.Ĭ. Both branches of the autonomic nervous system innervate most organs with the same function so that an organ will continue to function if one branch is damaged.ī. parasympathetic What is meant by dual innervation in the autonomic nervous system?Ī. initiating and maintaining activity and maintaining homeostasis Which branch of the peripheral nervous system is most active during rest?ĭ. initiating and maintaining activity and maintaining homeostasis D. to maintain the body at rest and maintain homeostasisĭ. inhibiting the sympatho-adrenal response and maintaining homeostasisĬ. to initiate the flight-or-fight response and disrupt homeostasisī. What is the purpose, or function, of the sympathetic nervous system?Ī. Acetylcholine is broken down by acetylcholinesterase within the cell membrane of the post-synaptic effector cell while norepinephrine is broken down by the mitochondria of the pre-synaptic neuron. Acetylcholine is broken down by acetylcholinesterase within the cell membrane of the pre-synaptic neuron while norepinephrine is broken down by the mitochondria of the post-synaptic effector cell. Acetylcholine is broken down by acetylcholinesterase within the cell membrane of the post-synaptic effector cell while norepinephrine is broken down by the mitochondria of the pre-synaptic neuron.ĭ. Acetylcholine is broken down by monoamine oxidase within the post-synaptic effector cell while norepinephrine is broken down by the mitochondria of the pre-synaptic neuron.Ĭ. What is the difference between the methods of clearing acetylcholine and norepinephrine at the autonomic neuroeffector junctions?Ī> Acetylcholine is broken down by the mitochondria within the post-synaptic effector cell while norepinephrine is broken down by adrenergic esterase of the pre-synaptic neuron.ī. Reduce sympathetic stimulation and reduce heart rate and blood pressure. Increase sympathetic stimulation and reduce heart rate and blood pressure. Reduce sympathetic stimulation and reduce heart rate and blood pressure.ĭ. Increase sympathetic stimulation and increase heart rate and blood pressure.Ĭ. Reduce sympathetic stimulation and increase heart rate and blood pressure.ī. The preganglionic neurons of the parasympathetic nervous system either originate in the brainstem or the sacral spinal cord. The parasympathetic neurons arise from two nerve plexi one found in the brainstem and the other found in the lumbar region. The parasympathetic neurons consist of the cranial (cranio) nerves and the pelvic nerves (sacral) that originate at the appropriate levels of the spinal cord.ĭ. The preganglionic neurons of the parasympathetic nervous system originate from several nuclei found running from the brain (cranio) to the lumbar region (sacral).Ĭ. The preganglionic neurons of the parasympathetic nervous system either originate in the brainstem or the sacral spinal cord.ī. sympathetic chains Why is the parasympathetic nervous system referred to as the craniosacral division of the autonomic nervous system?Ī. What structure does the sympathetic nervous system use to produce action in many different target organs at the same time?ĭ.
