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.

Once a sympathetic preganglionic axon reaches a paravertebral ganglion, it can: pass through the paravertebral ganglion without synapsing until it reaches the prevertebral ganglion. O True False
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…
