 | | The Sympathetic Efferent Fibers of the Vagus Nerve are supposed to arise in the dorsal nucleus (nucleus ala cinerea). | | | The Thoracolumbar Sympathetics - The thoracolumbar sympathetic fibers arise from the dorso-lateral region of the anterior column of the gray matter of the spinal cord and pass with the anterior roots of all the thoracic and the upper two or three lumbar spinal nerves. | | | The preganglionic parasympathetic cell bodies are situated in the brain stem (cranial parasympathetic) and in the sacral spinal cord (sacral parasympathetic). |

| | Metabolic modulation of sympathetic vasoconstriction in human skeletal muscle: role of tissue hypoxia -- Hansen et al. ... |
| | Although the precise mechanism by which muscle hypoxia attenuates sympathetic control of oxygenation remains to be determined, our data suggest that hypoxia-induced activation of the cyclooxygenase pathway is not essential. | | | In contrast, the response to forearm vascular occlusion was not affected by FPP. | | | Recordings of multiunit efferent postganglionic sympathetic nerve activity (SNA) to the skeletal muscle bed were obtained with unipolar tungsten microelectrodes inserted selectively into muscle nerve fascicles of the peroneal nerve posterior to the fibular head by microneurography (Vallbo et al. |

| | British Medical Journal: Interrupting the sympathetic outflow in causalgia and reflex sympathetic dystrophy - Editorial |
| | Thus, in contrast to the pain relief commonly achieved by sympathetic blockade in disorders such as pancreatic cancer and attributable to blocking visceral afferent nerves,[6] there is little if any evidence that interrupting the sympathetic supply is more effective than placebo in alleviating the pain of causalgia and reflex sympathetic dystrophy. | | | Some individual patients, however, may benefit from sympathetic blockade, and there may also be groups of patients with specific clinical features, in particular allodynia,[12] whose pain is more likely to respond and who perhaps account for those reports of successful relief of pain. | | | The involvement of the sympathetic nervous system in causalgia and reflex sympathetic dystrophy, which forms the rationale for treatment by sympathetic interruption, has been questioned,[14] and the issues discussed here raise further questions. |

| | The ANS |
| | The sympathetic nerves reach their end-organs through more devious pathways down the spinal cord to clusters of sympathetic nerve bodies (ganglia) alongside the spine where the messages are relayed to other nerve bodies (or neurons) that travel to a large extent with the blood vessels to all parts of the body. | | | Through these nervous pathways, the autonomic nerves convey stimuli resulting in largely unconscious, reflex, bodily adjustments such as in the size of the pupil, the digestive functions of the stomach and intestines, the rate and depth of respiration and dilatation or constriction of the blood vessels. | | | The afferent nerves subserving both systems convey impulses from sensory organs, muscles, the circulatory system and all the organs of the body to the controlling centers in the medulla, pons and hypothalamus. |

| | Human Sympathetic Nervous System |
| | Thinking back to the anatomic diagrams of the two subsystems, remember that the sympathetic has a major somatic distribution via grey rami to the spinal nerve branches that is entirely lacking in the parasympathetic pathway. | | | Recall from our study of the spinal cord that all motor axons leave their spinal origins by way of the ventral roots in mammals. | | | The general opinion is that there are no specialized sensory receptors in the genital organs involved with sexual excitation and gratification, but the unique sensory response leaves this question open. |

| | The sympathetic nerve "chain" is formed by a plexus of nerves located next to the ribs in the chest. | | | Different surgeons have been trained in different techniques and all appear to be effective in a high percentage of cases. | | | In the past, this often required a moderate to large sized incision in the chest which required cutting muscles and separating ribs to expose the sympathetic chain. |

| | If this 'sympathetic block' eases the pain, then it is likely that the sympathetic nervous system is contributing to the pain. | | | When a diagnostic sympathetic block is performed and is successful, then the pain relief lasts only a short time. | | | On the whole, blood tests are not useful, but the doctor will probably ask for certain blood tests, mainly to exclude other causes of pain and swelling. |

| | Introduction to Cardiovascular Pharmacology |
| | Increases in sympathetic tone result in increased peripheral vascular resistance, increeased venous tone, increased heart rate, and increased contractility of the myocardium. | | | A rise in mean arterial pressure causes an increase in baroreceptor neuronal activity and gives rise to an increase in vagal tone (activity of the vagus nerve) and a decrease in sympathetic tone. | | | Short-term changes in blood pressure (time frame of seconds to minutes) are mediated by the autonomic nervous system. |

| | Sympathetic System |
| | Autonomic system neural pathways regulate the activities of the internal organs and differ from somatic pathways by having two motor neurons that travel peripherally rather than one. | | | Many internal organs are stimulated by both systems. | | | The autonomic nervous system has two main parts, the sympathetic and the parasympathetic systems, which differ both structurally and functionally from each other. |
