Concept explainers
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?

- Watch this video (http://openstaxcollege.org/l/3Dmovies) to learn about the side effects of 3-D movies. As discussed in this video, movies that are shot in 3-D can cause motion sickness, which elicits the autonomic symptoms of nausea and sweating. The disconnection between the perceived motion on the screen and the lack of any change in equilibrium stimulates these symptoms. Why do you think sitting close to the screen or right in the middle of the theater makes motion sickness during a 3-D movie worse?arrow_forwardFigure 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.arrow_forwardWhich of the following could be used to describe the parasympathetic nervous system? Select all that apply. Short preganglionic, long postganglionic fibers. O long preganglionic, short postganglionic fibers. Known to be active during "rest and digest" responses. Stimulates ciliary muscles of the eye, which makes the lens bulge for close vision. O Active during "fight or flight" responses. increases heart rate « Previous Nextarrow_forward
- Which of the statements about neurotransmitters given below is incorrect? О а. Orexin-producing cells in the locus querulous of the pons activate many different areas of the brain including the cerebral cortex, hippocampus, thalamus, cerebellum, and the pons and medulla as well. b. Blocking acetylcholine appears to reduce arousal levels, while procedures designed to increase acetylcholine production increase signs of arousal. Acetylcholine increases the general arousal of the cortex O C. Research has shown that Seratonin cells are most active during waking and decrease during sleep. In addition, serotonin seems to facilitate automatic behaviors such as chewing, pacing, or grooming.arrow_forwardmagine you are a student studying for your pharmacy technician certification exam.
