Neural control of the circulation.
The purpose of this brief review is to highlight key concepts about the neural control of the circulation that graduate and medical students should be expected to incorporate into their general knowledge of human physiology. The focus is largely on the sympathetic nerves, which have a dominant role in cardiovascular control due to their effects to increase cardiac rate and contractility, cause ...
متن کاملSympathetic control of coronary circulation.
The sympathetic control of left circumflex coronary blood flow was studied by stellate ganglion and hypothalamic stimulation. Flow was measured acutely in dogs under chloralose or pentobarbital anesthesia by an electromagnetic flowmeter. Coronary vasoconstriction was observed when the left stellate ganglion was stimulated after blocking beta receptors with propranolol or INPEA. The possibility ...
متن کاملNeurogenic Control of Cerebral Circulation
Neurogenic Control of Cerebral Circulation • A review of recent literature provides evidence that cerebral vessels are innervated with myelinated and nonmyelinated nerves. Among the latter, adrenergic nerves are readily demonstrated. Stimulation of cervical sympathetics produces a reduction in cerebral blood flow attributable to constriction of vessels in the neck and on the cerebral surface. I...
متن کاملControl of the foetal circulation.
Foetal cardiac output is high, and the heart has not been shown to have the sustained reserves demonstrated in the adult heart. About 40% (approximately 200 ml. kg body weight-1. min-1) of the combined output of both ventricles (CVO) in unanaesthetized foetal lambs in late gestation is directed to the umbilical circulation. At least one-half of the systemic flow (approximately 300 ml. kg body w...
