NO and central cardiovascular control: a simple molecule with a complex story.
The 1998 Nobel Prize in Physiology or Medicine recognized the great contributions of Robert Furchgott, Louis Ignarro, and Ferid Murad through “their discoveries concerning nitric oxide as a signaling molecule in the cardiovascular system.” Furchgott’s earlier work describing a vasodilatory factor that was activated by acetylcholine acting on an intact endothelium not only set the stage for subs...
متن کاملCentral nervous integration of cardiovascular control.
SUMMARY In this account an attempt has been made to identify integrative interactions in the control of the cardiovascular system. Three main sites of such interaction have been considered, the nucleus of the tractus solitarius (NTS), the vagal preganglionic supply to the heart and sympathetic pre-ganglionic neurones. In the case of the NTS the extent and range of afferent inputs from cardiovas...
متن کاملCentral Serotonergic Control of Cardiovascular Reflexes
Central serotonergic neurones control reflex parasympathetic outflow to the heart, airways and bladder in a number of species, and different 5-HT receptor subtypes are involved in this effect. 5-HTja and 5 -HT3 receptors in the brainstem facilitate these reflexes, whilst 5-HTjb/id, 5-HT2 and 5 -HT4 receptors inhibit them. Recently, central 5 -HT7 receptors have been implicated in bladder reflex...
متن کاملCentral Sympathetic Control of Cardiovascular Function
Cardiovascular function is regulated by a dynamic balance comprised of sympathetic and parasympathetic influences. Sympathetic regulatory centers include the rostra ventrolateral medulla (RVLM) and paraventricular nucleus of hypothalamus (PVN). Pre-sympathetic neurons (PSNs) in these centers project directly to sympathetic preganglionic neurons in the intermediolateral nucleus of the thoracic s...
متن کاملCentral control of cardiovascular function during sleep.
There is increasing evidence that cardiovascular control during sleep is relevant for cardiovascular risk. This evidence warrants increased experimental efforts to understand the physiological mechanisms of such control. This review summarizes current knowledge on autonomic features of sleep states [non-rapid-eye-movement sleep (NREMS) and rapid-eye-movement sleep (REMS)] and proposes some test...
