Sympathetic outflows from cervical spinal cord in the dog.
In some dogs there are preganglionic fibers leaving the cervical spinal cord through the ventral roots of the lower cervical nerves. When these fibers are stimulated electrically in the anesthetized dog with skeletal muscle paralysis (induced by decamethonium), the effects are vasoconstriction in the front footpad, cardiac acceleration and augmentation, and a rise in arterial blood pressure.
متن کاملSympathetic-parasympathetic interactions in the heart.
We determined the influence of differences in the time of initiation of sympathetic and vagal stimulation (both at 10 Hz) on the cardiac autonomic interactions in 16 open-chest anesthetized dogs. We always ended the concurrent sympathetic and vagal stimulations simultaneously. Sympathetic stimulation alone for 1 minute increased heart rate by 90±7 (mean+SEM) beats per minute, and vagal stimulat...
متن کاملSympathetic postganglionic cholinergic fibres.
When the postganglionic fibres to the nictitating membrane are stimulated in a cat treated with reserpine, the membrane contracts. The contraction is increased after the injection of eserine and is abolished with atropine. Thus the fibres stimulated appear to be cholinergic. When the splenic nerve is stimulated in a cat treated with reserpine there is similar evidence of the presence of choline...
متن کاملStereological Study on the Neurons of Superior Cervical Sympathetic Ganglion in Diabetic Rats
Background: Most research on autonomic dysfunction of diabetes mellitus is conducted on ganglions innervating gastrointestinal (GI) tract and there are limited works focusing on cervical sympathetic ganglia. The effects of diabetes mellitus (DM) on the neurons of superior cervical sympathetic ganglion (SCSG) are investigated by stereological methods. Material and Methods: Female rats (n=72) ran...
متن کاملThe location and function of respiratory fibres in the second cervical spinal cord segment: respiratory dysfunction syndrome after cervical cordotomy.
After high cervical percutaneous cordotomy for pain in malignant disease, 12 patients died during sleep at postoperative intervals between 1 and 8 days. Nine died after a first cordotomy and three after a second (contralateral) procedure. All except one had known pulmonary disease before operation. The operated segment of the spinal cord (C2) was studied histologically after death. Superpositio...
