front 1 Sympathetic and parasympathetic fibers serve the same organs and structures. How can they exert opposite effects? | back 1 They release different neurotransmitters, which bind to different receptors. |
front 2 Name 3 structures that receive sympathetic but not parasympathetic innervation. | back 2 - Adrenal glands |
front 3 A pelvic splanchnic nerve contains | back 3 preganglionic parasympathetic fibers |
front 4 Sympathetic | back 4 - postganglionic fibers secrete norepinephrine; adrenergic fiber - short preganglionic axon; long postganglionic axon - arises from spinal nerves T1-L3 - "Fight-or-flight" system |
front 5 Parasympathetic | back 5 - postganglionic fibers secrete acetylcholine; cholinergic fiber - long preganglionic axon; short postganglionic axon - arises from cranial and sacral nerves - normally in control - has more specific control |
front 6 Describe how EDA/GSR can be correlated with activity of the autonomic nervous system. | back 6 The autonomic nervous system is integrated by emotions (stress, pain, feelings). These changes change heart, respiration, blood pressure, & more changes occur in the skin. All these can be measured by GSR since it is measurement of changes in skin due to autonomic stimulation. |
front 7 Why might this be an exact tool for testing the sincerity and honesty of a subject? | back 7 Its failure rate is far too high to provide the scientific or legal certainty. If it is based on skin and emotional changes, people feel different on different topics/subjects so it could give a false reading. |
