- Watch this video (http://openstaxcollege.org/l/ emotions) to learn about physical responses to emotion. The autonomic system, which is important for regulating the homeostasis of the organ systems, is also responsible for our physiological responses to emotions such as fear. The video summarizes the extent of the body’s reactions and describes several effects of the autonomic system in response to fear. On the basis of what you have already studied about autonomic function, which effect would you expect to be associated with parasympathetic, rather than sympathetic, activity?arrow_forwardIn some cases, people who suffer from depression can be prescribed a serotonin re-uptake inhibitor if they are determined to be resistant to behavioral treatment. Explain how a serotonin re-uptake inhibitor would alter concentrations of serotonin in the brain. Would this change occur at all synapses within the brain? Why or why not?arrow_forwardDescribe the effects of the drug atropine and explain these effects in terms of the actions of the parasympathetic system.arrow_forward
- Heroin (diamorphine) is: O an opioid receptor antagonist. O a long-acting opioid agonist that produces dysphoria. O a drug that is metabolised in humans to morphine. a drug with high liability for physical dependence and low liability for psychological dependence. Question 4 Cocaine exerts sympathomimetic activity by: O acting directly as an agonist at alpha 1-adrenoceptors. inhibiting the re-uptake of noradrenaline at axon terminal sympathetic neurons. O inhibiting alpha 1-adrenoceptors. O inhibiting the breakdown of noradrenaline by monoamine oxidase.arrow_forwardOne type of poison arrow frog toxin binds specifically to nicotinic cholinergic receptors and causes tetanic paralysis of the muscle. Would the poison arrow frog toxin increase or decrease autonomic output? Explain your answer choice based on neurotransmitters and receptors on the pre-and postganglionic neurons in the sympathetic and parasympathetic nervous system.arrow_forwardAmong the followings which does not indicate the stimulation of parasympathetic system? A. Contriction of skeletal muscle blood and vasodilation of renla blood B. Excitation of the blood flow to the kidneys and smooth muscles of Gl tract C. Inhibition of heart rate and amooth muscles of the urinary bladder Excitation of the smooth muscles of the urinary bladder and Gl tractarrow_forward
- Which 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_forwardcompare and contrast the differences between the sympathetic and parasympathetic nervous systems. Use the following scenarios: Scenario 1: You are walking outside late at night and you hear something in the bushes as you approach your home. Which system will dominate and what physiological changes will occur? Scenario 2: You have just finished a big dinner and now you are relaxing in your recliner to watch the big ball game. Which system will dominate and what physiological changes will occur? Be sure to at least include what happens to heart rate, blood pressure, and digestion. You may include other physiological variables as well. "Not a homework assignment"arrow_forwardChronic stress has been suggested to be a contributing factor to Major Depressive Disorder. Explain the mechanisms by which the nervous system triggers stress responses, giving examples of the structures and molecules involved in these responses. Discuss how chronic stress might contribute to Major Depressive Disorder. Explain and evaluate the evidence supporting a role for chronic stress in the disorder.

The subjects were shown negative, positive, and neutral images. The subjects with limited rest remembered most of the negative images but only half of the positive and neutral images.The structures of the brain affected by long-term stress and sleep deprivation are, respectively: Select one: a.
