Figure 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.
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…
In the sympathetic division of the autonomic system: preganglionic neurons originate in the thoracolumbar segments of the cord the preganglionic neurons are unmyelinated the preganglionic neurons are long the neurotransmitter released by the preganglionic neurons is norepinephrine
For which of the following systems is the neurotransmitter acetylcholine released by neurons at the target tissue? true only for the sympathetic division true only for the parasympathetic division true for both divisions false for both divisions
Which of the following is characteristic of parasympathetic ganglia the ganglia are formed of the cell bodies of general somatic efferent neurons O the ganglia are formed of the cell bodies of preganglionic neurons parasympathetic autonomic ganglia are ALL found within the walls of the effector glands or organs synapses between preganglionic and postganglionic neurons are formed within the autonomic ganglia
Which of the following statements regarding autonomic nervous system function is false? autonomic efferent axons may be found in both cranial and spinal nerves autonomic efferent pathways are usually two neuron pathways preganglionic and postganglionic autonomic efferent neurons synapse in autonomic ganglia O cranial nerves III, VII, IX, and X carry preganglionic parasympathetic axons O none of the above are false (all are true)
Which of the following is CORRECT regarding the sympathetic ganglia? Group of answer choices It is encapsulated by myeline sheath. It is a network of branching interconneted fibers. It is responsible for regulating the parasympathetic response. It receives nerve fibers arising from the thoracic spinal cord.
all of the following apply to the autonomic nervous system except it operates on an involuntary basis it consists of sympathetic and parasympathetic divisions it does not include cranial nerves it is composed of preganglionic and postganglionic neurons
Sympathetic nerve activity refers best to which of the following aspect of sympathetic nerves? Group of answer choices Number of action potentials generated Number of sensory potentials received The speed of axonal conduction Saltatory conduction pattern of the axon
All the following regarding sympathetic nervous system are true except: * It is involved in stress & emergency conditions. It has a vasodilatory effect on skeletal muscle blood vessels during rest. All its preganglionic fibres are cholinergic. Its stimulation increases the cardiac properties. E O Its stimulation causes urine retention.
Once a sympathetic preganglionic axon reaches a paravertebral ganglion, it can: synapse with a post- ganglionic neuron, at the same spinal segment level. O True False
