Description



Which of these is NOT INNERVATED by the splanchnic nerves?

superior cervical ganglion  Which response is NOT part of sympathetic activation? decreased muscle tone 

Which of the following effectors is innervated by neurons that synapse in the collateral ganglia?

intestine 

What part of the autonomic nervous system is represented in the image?

sympathetic division  Which of the following is NOT supplied by cervical sympathetic chain ganglia? spleen 

What is the effect of neurotransmitters released at the area marked by the arrow?

They are released into the blood and produce long-lasting and widespread effects in the body. 

Which of these neurotransmitters is NOT released at sympathetic neuroeffector junctions?

atropine During an asthma attack, inhalers are used to dilate respiratory passages, making breathing easier. What type of adrenergic membrane receptor is targeted to cause this reaction? beta-2 receptor  Which of these substances is NOT a neurotransmitter at a sympathetic effector synapse? gamma aminobutyric acid (GABA) 



In what part of the given pathway is norepinephrine secreted?

from the varicosities of the postganglionic fiber  Which of the following is NOT a component of the parasympathetic nervous system? celiac ganglion  Parasympathetic outflow is ABSENT in which of these? cervical ganglia  When reviewing the general functions of the parasympathetic division, which of the following statements best summarizes the physiologic outcome? The parasympathetic division works at counterbalancing the sympathetic division by conserving energy and lowering metabolic rate.  Which of the following target organs will have its parasympathetic regulation impacted by damage to the sacral region of the spinal cord?



urinary bladder Where are the parasympathetic ganglionic synapses for the heart located?

within the heart itself

The parasympathetic nervous system releases _ ACETYLCHOLINE_ at ganglionic synapses and _ ACETYLCHOLINE_ at its neuroeffector junctions.  Nicotine, the highly addictive plant toxin, activates nicotinic receptors in the peripheral nervous system. This means it will __________. facilitate synaptic transmission at all autonomic ganglionic synapses  Which of these organs does NOT receive parasympathetic input? SKIN  Which of these is NOT a similarity between the parasympathetic and sympathetic nervous systems? Both use norepinephrine. 

 Which statement is correct? Sympathetic ganglia lie close to the spinal cord.  Even in the absence of a stimulus, autonomic motor neurons show a resting level of spontaneous activity. What is this called? autonomic tone  Which of these organs does NOT receive dual innervation? Sweet Glands 

Which of the following is most likely to be affected by being punched in the stomach?

 Celiac Plexus  Which of the following are true of visceral reflexes? short reflexes essential to digestive function long reflexes  Where is the headquarters of the autonomic nervous system? Hypothalamus  Which of the following is NOT an example of a visceral reflex? Tendon reflex



Which of the following is missing in a short reflex?

CNS component   Which of the following is an example of a skill memory? PLAYING PIANO During deep sleep, which of these changes is/are NOT normally observed? RAPID EYE MOVEMENT Why is LSD known as a powerful hallucinogenic drug? It activates serotonin receptors in the brain stem, hypothalamus, and limbic system, increasing the concentration of serotonin. Brain dopamine levels are important in all of these EXCEPT __________. Huntington's disease Which of the following is the most correct statement with regards to higher order function? If someone starts to fall asleep out of boredom, most likely the reticular activating system is not sending enough stimuli to keep the cerebral cortex activated. Terry has recently been diagnosed with an inherited form of depression. Which of the following is the most likely cause for the depression? Terry has a mutation in the enzyme involved in NE synthesis. Insomnia is considered a sleep disorder. Sleep technicians use a variety of techniques to determine the underlying cause(s) of this condition in an insomniac. Which of the following is NOT one of the causes of insomnia? Amnesia acetylcholine
