A Functional Study of Distribution of Cardiac Sympathetic Nerves.
RANDALL, WALTER C., DONALD V. PRIOLA, AND RICHARD H. ULMER. A functional study of distribution of cardiac sympathetic nerves. Am. J. Physiol. 205(6): 1227-1231. I g63.-In dogs with unilaterally sympathectomized hearts, the remaining intact stellate ganglion was electrically stimulated I 4-58 days following sympathectomy. Pressures were simultaneously recorded from all four chambers of the heart...
متن کاملPositional Relationship between Natural Killer Cells and Distribution of Sympathetic Nerves in Decidualized Mouse Uterus
Background: Uterine natural killer (uNK) cells are the most abundant leukocytes in pre-implantation endometrium and early pregnancy deciduas in humans and rodents. They are associated with structural changes in maternal spiral arteries but regulation of their re-cruitment and activation is incompletely understood. The major subpopulation of uNK cells in humans expresses CD56, the neural cell ad...
متن کاملFunctional significance of coactivation of vagal and sympathetic cardiac nerves.
Simultaneous recording of activity in the vagal and sympathetic supplies to the heart has revealed that in reflexly and centrally evoked activity these two "antagonists" do not necessarily change action reciprocally. Coactivation occurs in chemoreceptor reflexes and related reactions, upon stretching of the sinoatrial nodal region of the right atrium and when certain hypothalamic regions are st...
متن کاملDevelopment, maturation, and transdifferentiation of cardiac sympathetic nerves.
The heart is electrically and mechanically controlled as a syncytium by the autonomic nervous system. The cardiac nervous system comprises the sympathetic, parasympathetic, and sensory nervous systems that together regulate heart function on demand. Sympathetic electric activation was initially considered the main regulator of cardiac function; however, modern molecular biotechnological approac...
متن کاملThe augmentor action of the sympathetic cardiac nerves.
An augmentor action of the cardiac sympathetic nerves is demonstrated to elicit profound elevations in systolic blood pressure. Diastolic pressure does not rise in an equivalent amount and significant increase in pulse pressure occurs. This persists for a considerable time after removal of the stimulation. During stimulation of the left cardiac sympathetic, an augmentor action is often not acco...
