front 13 Emotions influence autonomic reactions primarily through integration in the ________. | back 13 hypothalamus |
front 14 All visceral organs receive dual innervation from both the sympathetic and parasympathetic divisions of the ANS. | back 14 False |
front 15 The sympathetic and parasympathetic divisions of the ANS have the same effect on most body organ systems. | back 15 False |
front 16 The "resting and digesting" division of the autonomic nervous system is the ________. | back 16 parasympathetic division |

front 19 Control of temperature, endocrine activity, and thirst are functions associated with the ________. | back 19 hypothalamus |
front 20 The autonomic nervous system may cause activation or inhibition, depending on the division that is active and the target that is affected. | back 20 True |

front 22 Which of the following is NOT associated with the parasympathetic division of the autonomic nervous system (ANS)? | back 22 emergency action |
front 23 Sympathetic responses generally are widespread because ________. | back 23 NE and epinephrine are secreted into the blood as part of the sympathetic response |
front 24 Which of the following is NOT an autonomic nervous system (ANS) effector? | back 24 skeletal muscle |
front 25 For which of the following activities is the parasympathetic nervous system generally responsible? | back 25 resting and digesting |
