- Classify the following characteristics to demonstrate your knowledge of differences between the sympathetic and parasympathetic divisions of the autonomic nervous system. Sympathetic Nervous System Most ganglia lie close to the spinal cord and form two chains of ganglia-one on each side of the spinal cord Increases intestinal motility and stimulates intestinal secretion Postganglionic axons are generally short Preganglionic axons are generally short Postganglionic axons release NE that binds to adrenergic receptors located on the effectors Decreases heart rate, contractility, and conduction velocity Ganglia lie within, or very close to, innervated organs Decreases intestinal motility and inhibits intestinal secretion Long preganglionic axons release ACh that binds to nicotinic receptors located within the ganglia Neurons leave the CNS from the thoracic and lumbar regions of the spinal cord Parasympathetic Nervous System Generalized activation is called the fight-or-flight response…arrow_forwardWhich of the following is not correct about the parasympathetic division? Select one: O A. parasympathetic nerves constitute a part of the autonomic nervous system O B. the neurotransmitter released by preganglionic neurons is acetylcholine O C. parasympathetic nerves always form synapses in ganglia near or within an internal organ O D. the neurotransmitter released by postganglionic neurons is acetylcholine O E. parasympathetic nerves exit the central nervous system at the thoracic and lumbar regions of the spinal cordarrow_forwardWhat is maladaptive neuroplasticity? Neuroplasticity that affect the autonomic nervous system Neuroplasticity that has adverse effects Neuroplasticity that only last a short time Neuroplasticity that is dormant and cannot be activatedarrow_forward
- Which of the following statements is true? Select one: O a. Cholinergic nicotinic receptors of autonomic ganglia are identical to N cholinergic receptors of neuromuscular junction O b. Some of the postganglionic sympathetic fibers are cholinergic O c. All of the visceral organs/structures have dual innervation (sympathetic and parasympathetic) O d. Adrenaline does not usually circulate in bloodarrow_forwardFigure 35.26 Which of the following statements is false? The parasympathetic pathway is responsible for relaxing the body, while the sympathetic pathway is responsible for preparing for an emergency. Most preganglionic neurons in the sympathetic pathway originate in the spinal cord. Slowing of the heartbeat is a parasympathetic response. Parasympathetic neurons are responsible for releasing norepinephrine on the target organ, while sympathetic neurons are responsible for releasing acetylcholine.arrow_forwardWhat are the main differences between the sympathetic and parasympathetic branches of the autonomic nervous system?arrow_forward

- Which of the following is not correct about the parasympathetic division? Select one: O A. the neurotransmitter released by preganglionic neurons is acetylcholine O B. parasympathetic nerves always form synapses in ganglia near or within an internal organ O C. the neurotransmitter released by postganglionic neurons is acetylcholine D. parasympathetic nerves constitute a part of the autonomic nervous system O E. parasympathetic nerves exit the central nervous system at the thoracic and lumbar regions of the spinal cord Next pagearrow_forwardParkinson's Disease Parkinson's disease is a neurological degenerative disorder that affects movement. Most people affected with Parkinson's disease demonstrate rigidity, slow movement, and shaking. The symptoms of Parkinson's disease occur when the cells that produce dopamine neurotransmitters die in the brain. Since most symptoms of Parkinson's disease are caused by insufficient dopamine in the brain, many Parkinson's drugs either temporarily replenish dopamine or mimic the action of dopamine. Explain how the signal transmission at a synapse in an individual with Parkinson's disease is different than an unaffected individual. 1. List the steps involved in an action potential moving from the axon terminal of the pre-synaptic neuron to the dendrites of the post-synaptic neuron. 2. Explain how the process is different in individuals affected with Parkinson's disease.arrow_forwardWhich of the following describe the myelination of the nervous system correctly? Please select all that apply. A) Caudal structures are myelinated before rostral structures. B) Myelination of the human central nervous system is not complete until around the age of 25 years. C) Sensory systems are myelinated before motor systems in the cerebral cortex. D) Myelination at different ages is not very predictive of behavioral differences.arrow_forward
