The sympathetic nerves have cancer-promoting effects on prostate cancer, breast cancer, and melanoma. On the other hand, while the parasympathetic/vagal nerves have cancer-promoting effects on prostate, gastric, and colorectal cancers, they have cancer-suppressing effects on breast and pancreatic ...
Developmental changes in the interactions of cholinergic and beta-adrenergic agonists on electrophysiologic properties of canine cardiac Purkinje fibers. The parasympathetic nervous system attenuates the effects of sympathetic interventions on the hearts of mature . Whereas the vagal mediator, (ACh), alone...
Lacrimation and nasal secretion during attacks of cluster headache appear to be due to massive trigeminal-parasympathetic discharge. In addition, the prese... PD Drummond - 《Cephalalgia》 被引量: 81发表: 2006年 How cluster headache is explained as an intracavernous inflammatory process lesioning sy...
The sympathetic and parasympathetic nervous systems, closely interconnected into the pelvic plexus which represents an integrative peripheral crossroad site, act in synergy to command physiological events occurring during ejaculation. Both sympathetic and parasympathetic tones are under the influence of sensory...
sympathetic nervous system- originates in the thoracic regions of the spinal cord; opposes physiological effects of the parasympathetic: reduces digestive secretions; speeds the heart; contracts blood vessels nervous system,systema nervosum- the sensory and control apparatus consisting of a network of ne...
The SD1 is related to fast beat-to-beat variability whereas SD2 is linked to long-term RR interval variability and is influenced by both sympathetic and parasympathetic components. Indexes of parasympathetic function are thought to be rMSSD, SDRR, pNN50% and HF fluctuations in heart rate (in ...
Inward-attention meditation increases parasympathetic activity: a study based on heart rate variability. Biomed Res 2008; 29: 245–250. 22 Viskoper R, Shapira I, Priluck R, Mindlin R, Chornia L, Laszt A, Dicker D, Gavish B, Alter A. Nonpharmacologic treatment of resistant hypertensives by...
The sympathetic and parasympathetic nervous systems rest on either side of a wobbling scale; each system remains active in the body and helps counteract the actions of the other. If the opposing forces are mostly balanced, the body achieves homeostasis and operations chug along as usual. But dise...
decreased during the cold pressor. The balance of aqueous humor production and outflow determines IOP. Previous studies discussed that parasympathetic and sympathetic innervation involved influenced both aqueous humor production and outflow. But the precise underlying mechanism of any observed changes in ...
In this regard, it is important to note that the effect of sympathetic regulation of CNS vascular tone may not be uniform across brain regions10,11, and that parasympathetic mechanisms may contribute as well43. Furthermore, sympathetic vascular tone is likely to have a co-modulating neuronal ...
