Abstract The sympathetic nervous system combines with the parasympathetic system to form the autonomic nervous system, and together they help control bodily functions that are unconsciously directed. The sympathetic nervous system (SNS) extends throughout the whole body and allows the body to prepare for physical activity necessary in ...

The Sympathetic Nervous System of Anamniotes
Brain, Behavior and Evolution, 2007The sympathetic nervous system develops as an evolutionary trait with gnathostomes (jawed vertebrates), but not with agnathan fishes (i.e., hagfishes and lampreys). Organization of the sympathetic preganglionic neuronal columns is different in teleosts and anurans. In the teleosts so far examined, the majority of sympathetic preganglionic neurons (SPNs)

Sympathetic nervous system regulation of immunity
Journal of Neuroimmunology, 2004An immune response can be regulated by a variety of hormones and transmitters, although it is not yet clear under what sets of circumstances such immunoregulation occurs, and in which direction immune function might be altered. That the sympathetic nervous system (SNS) plays a role in immune regulation is inferred from four lines of evidence:

The Sympathetic Nervous System and Pain
NeuroMolecular Medicine, 2007The sympathetic nervous system (SNS) and pain interact on many levels of the neuraxis. In healthy subjects, activation of the SNS in the brain usually suppresses pain mainly by descending inhibition of nociceptive transmission in the spinal cord. Furthermore, some experimental data even suggest that the SNS might control peripheral inflammation and ...

THE SYMPATHETIC NERVOUS SYSTEM
Archives of Neurology & Psychiatry, 1941In a previous communication 1 we called attention to the fact that the sensation from a sympathectomized zone of skin when exposed to cold differs considerably from that of a normally innervated zone. Seven patients were taken into a refrigerator at a temperature of 0 to 4 C. The patients were nude except for a loin cloth.

Sympathetic Nervous System and Hypertension
1974The role of the sympathetic nervous system in the pathogenesis of essential human hypertension is not yet established [6, 7, 10, 11, 25, 36]. In spite of this the majority of drugs currently used in the treatment of human hypertension act by modifying peripheral and/or central adrenergic mechanisms [27].

Sympathetic nervous system and glioma growth
European Journal of Cancer and Clinical Oncology, 1986C-6 glioma cells possess beta-adrenergic receptors on the cell surface. Activation of beta-adrenergic receptors with beta-adrenergic agonists increases intracellular levels of cAMP and leads to differentiation of C-6 glioma cells in vitro. The present study shows that growth of C-6 glioma tumor in rats with ablated sympathetic nervous system is ...

Sympathetic nervous system modulates macrophage function
International Journal of Immunopharmacology, 1992We have reported previously that sympathectomy augments immune responses in mice and rats. In the present study, we show that ablation of the sympathetic nervous system augments macrophage function as measured by increased TNF secretion. We also show that a factor present in the sympathetic ganglia of newborn rats, suppresses secretion of TNF by LPS ...

Peptides and the sympathetic nervous system
Pharmacological Research Communications, 1969Several workers have observed that under certain conditions kinins, although acting directly on blood vessels causing vasodilatation to produce hypotension, sometimes increase arterial blood pressure as well. Croxatto, Belmar, Pereda and Labacea (1962) reported such an effect when bradykinin was injected into rats with low blood pressure. These authors
