He further explained that if their hypothesis is proven right then arterial stiffness and baroreceptor signaling will become hotspot targets for the treatment of high blood pressure and the development of new medicines and medical devices.
Moreover, our findings strongly suggest that NADH-stimulated RMSAP might be under the inhibitory control of aortic baroreceptors, suggesting again that this response could be mediated by an increase in baseline efferent RSNA.
As the baroreceptors involved in this reflex regulation are effective only at buffering short term changes, major perturbations in autonomic nervous system activity would be evident only immediately after exercise cessation (Rowell, 1993).
Persistent hypotension can be caused by the effect of the stent on the carotid sinus baroreceptors (Trocciola et al.
Syncope suggests development of complications such as cardiac tamponade, obstruction of cerebral vessels or activation of cerebral baroreceptors.
Osmoreceptors in the hypothalamus and heart/blood vessel baroreceptors detect changes in plasma concentrations, producing or reducing anti-diuretic hormone (ADH) concentrations to increase, or decrease water absorption respectively (von Duvillard, 2004).
The baroreceptors are activated by the resultant increase in arterial blood pressure and act to buffer the vasoconstriction through dilation of vascular beds above the lesion level (with intact central control) and through reduction in HR (vagal innervation to the heart is unaffected by SCI).
The CVRx Rheos Baroreflex Hypertension Therapy System is an investigational implantable device that stimulates baroreceptors in the arterial walls of the carotid sinus.
Brain Buttons lie directly above and may stimulate the baroreceptors in the carotid artery, the hand on the navel brings attention to the gravitational centre of the body, thus promoting a kinesthetic base for movement and activity (7,17).
When the baroreceptors sense low blood pressure, they generate signals that cause nerves of the autonomic nervous system to speed up heart rate and constrict blood vessels.
Osmoreceptors in the hypothalamus itself cause the pituitary to increase ADH levels when plasma osmolality increases as little as 1-2% [2,7] Baroreceptors, especially in the heart and the carotid sinus, [10] monitor changes in blood volume and pressure and indirectly signal the hypothalamus to regulate ADH according to perceived changes.
Critical functions of the organism as a whole comprise three distinct and complementary biological categories: 1) vital functions of spontaneous breathing and autonomic control of circulation; 2) integrating functions that assure homeostasis of the organism, including the appropriate physiologic responses to baroreceptors, chemoreceptors, neuroendocrine feedback loops, and similar control systems; and 3) consciousness, which is required for the organism to respond to requirements for hydration, nutrition, and protection, among other needs.
Some baroreceptors are grouped together in concentrated areas in the aortic arch and report their information to the brainstem via fibres in the vagal nerve.
