What would be the advantage to a wolf in having its sympathetic nervous system stimulate the piloerector muscles? What happens in a human when the sympathetic system stimulates these muscles?
Scientists have suggested that the autonomic nervous system is not well-adapted to modern human life. How is the sympathetic nervous system an ineffective response to the everyday challenges faced by modern humans?
Mr. Putuu has been diagnosed with Horner syndrome, which is caused by dysfunction of the sympathetic neurons in the superior cervical ganglion that innervate structures of the head, face, and neck. What symptoms is Mr. Chevalier likely to face due to his disease? Explain.

- Malathion is an insecticide commonly used in the horticultural industry. Many homeowners apply this chemical to their trees to rid them of infestation by aphids or other insects. Malathion is classified as an organophosphate insecticide. Exposure to malathion is very dangerous to humans and animals because it acts as an irreversible inhibitor of acetylcholinesterase. Predict what might happen to synaptic communication between cholinergic neurons if an individual or animal was poisoned with malathion, and clearly describe the mechanisms at work.arrow_forwardFor 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 divisionsarrow_forwardMr. Putuu has been diagnosed with Horner syndrome, which is caused by dysfunction of the sympathetic neurons in the superior cervical ganglion that innervate structures of the head, face, and neck.

- 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 the autonomic nervous system, AChEls will increase activity of the: a. parasympathetic activity b. sympathetic activity C. both sympathetic and parasympathetic activityarrow_forwardImagine that you're hiking in the mountains one afternoon with friends. As you turn to the corner, you come across a mother bear and her cubs standing in the middle of the trail. A. Identify the specific division of the nervous system that is responsible that is responsible for the body's response to this situation. Explain B. Describe at least four physiological responses you might have upon seeing the bears. C. Indicate the division of the nervous system that is responsible for returning the body back to equilibrium after the event is over Explainarrow_forward
- Which of the following is an example of antagonistic control? O The parasympathetic nervous system originates from the brain stem and pelvic nerves, while the sympathetic arises from the thoracic and lumbar spinal cord. O Sympathetic stimulation causes renin secretion by the kidneys, but the kidneys are not innervated by the parasympathetic nervous system. O Parasympathetic stimulation causes bronchoconstriction, while sympathetic stimulation causes bronchodilation. O The vagus nerve innervates much of the viscera, changing the function of each of them independently of the others.arrow_forwardThe ____ receives a large amount of information from the amygdala. It's the final destination for most of the brain's information about emotion before action is taken. For this reason, patients with damage to this region often struggle to make decisions, especially when those decisions involve avoiding risks or learning from reinforcement and punishment. A) ventromedial prefrontal cortex B) posterior parietal cortex C) anterior insular cortex D) anterior cingulate gyrusarrow_forwardSympathetic innervation can have pro- and anti- inflammatory effects. Which of the following statements does not support this suggestion relative to a mouse model of inflammatory bowel disease (IBD). O Mice lacking the beta2-adrenergic receptor were less susceptible to this experimental IBD Catecholamines acting on alpha2-adrenoreceptors led to proinflammatory (IL-1beta, IL-6, and TNF-alpha) production worsening the IBD in mice Mice lacking the beta2-adrenergic receptor were more susceptible to this experimental IBDarrow_forward
- The most important reward circuit in the brain is the mesolimbic pathway. Dopaminergic neurons originate in the _____ and connect to the _____ and other structures. A) hippocampus; amygdala B) amygdala; prefrontal cortex C) ventral tegmental area (VTA); nucleus accumbens D) nucleus accumbens; prefrontal cortexarrow_forwardRead the statements given below. (i) Cell bodies of pseudounipolar neurons lie in dorsal root ganglion (ii) Na+/K+ pump transports 2 Na+ outwards for 3 K+ into the neuronal cell for maintaining resting potential (iii) Hypothalamus has control centres for hunger thirst, satiety and respiration (iv) Flowing of tears while peeling and cutting onions is a case of conditional reflex. How many of the above statements are false? 1.One 2.Three 3.Two 4.Zeroarrow_forwardHello, May I get help on this question very soon please? I do not understand it. Question: When your body mounts a sympathetic response, it causes the smooth muscle in your bronchioles to relax and dilate (get wider). By contrast, a parasympathetic response causes the smooth muscles in your bronchioles to contract and constrict (get narrower). This seems strange because fight-or-flight responses seem like they should upregulate activity and cause more contractions. A benefit of bronchiole dilation during fight or flight responses is that it...(see image)arrow_forward
