Modulation of Calcitonin, Parathyroid Hormone, and Thyroid Hormone Secretion by Electrical Stimulation of Sympathetic and Parasympathetic Nerves in Anesthetized Rats
The thyroid and parathyroid glands are dually innervated by sympathetic (cervical sympathetic trunk [CST]) and parasympathetic (superior laryngeal nerve [SLN]) nerve fibers. We examined the effects of electrical stimulation of efferent or afferent nerve fibers innervating the thyroid and parathyroid glands on the secretion of immunoreactive calcitonin (iCT), parathyroid hormone (iPTH), 3,3',5-t...
متن کاملResponses of sympathetic nerves to programmed ventricular stimulation.
Ventricular arrhythmias generally result in a decrease in arterial pressure and increases in atrial and ventricular filling pressures which would be expected to induce reflex changes in efferent sympathetic nerve activity to the heart and peripheral circulation. Experiments were performed in 14 anesthetized dogs in order to determine whether programmed ventricular stimulation produces changes i...
متن کاملLocalized myocardial responses to stimulation of cardiac sympathetic nerves.
Myocardial contractile force was recorded at three to five positions on the canine heart while progressively more distal portions of the cardiac sympathetic nerves were electrically stimulated. When the electrodes were applied directly to the stellate ganglion or to the ansa subclavia, positive inotropic responses were generally observed on all of the test regions of the heart. However, when mo...
متن کاملStimulation of the cervical sympathetic nerves increases intraocular pressure.
PURPOSE To test the hypothesis that a moderate electrical stimulation of the cervical sympathetic nerves in rabbits can increase intraocular pressure (IOP). METHODS Electrical stimulations of the cervical sympathetic nerves were performed in anesthetized and conscious rabbits. Intraocular pressure, pupil size, and concentrations of aqueous humor components were monitored. RESULTS In urethan...
متن کاملPressor reflexes produced by stimulation of afferent fibers in the cardiac sympathetic nerves of the cat.
Afferent fibers in cardiac sympathetic nerves were stimulated electrically in an attempt to evoke circulatory reflexes. A pressor response was always elicited during stimulation of the central end of the cut left inferior cardiac or pericoronary nerve in vagotomized intact-brain or spinal cats. The maximum blood pressure rise was 21.5 mm Hg during inferior cardiac nerve stimulation and 14.1 mm ...
