The Sympathetic Innervation of the Oviduct in the Rat
Acta Physiologica Scandinavica, 1969AbstractThe adrenergic innervation of the rat oviduct was studied by fluorescence microscopy. The outer half of the circular muscle layer was penetrated by a thin net of adrenergic nerve terminals throughout the isthmus. Adrenergic nerve terminals were scarcely seen in the muscular wall of the ampulla.

Sympathetic Innervation of the Tongue in Rats
ORL, 2004We employed a glyoxylic catecholaminergic histofluorescence method to study the sympathetic innervation present in the rat tongue. One percent neutral red was used as a counterstain. Many noradrenergic fibers were demonstrated around the blood vessels, muscles, glands and submucosa of the tongue, but not in the epithelium or papilla. In a group of rats

NEUROCHEMISTRY OF THE SYMPATHETIC INNERVATION TO THE UTERUS
Clinical and Experimental Pharmacology and Physiology, 1988SUMMARY1. The uterus is supplied by numerous noradrenergic sympathetic nerve fibres, which supply the intramural vasculature and also, in some species at least, the myometrium.2. Pregnancy is associated with progressive loss of catecholamine from these nerves.

Sympathetic innervation of the median eminence
Brain Research, 1984Bilateral removal of the superior cervical ganglia (SCG) decreases the adrenaline (NE) content of the median eminence. Bilateral removal of the SCG and bilateral deafferentation of the medial basal hypothalamus (MBH) together induce a greater decrease of NE content of the median eminence than that resulting from either one of the operations performed ...

Sympathetic innervation of the jejunal villus
Acta Histochemica, 1983Using fluorescent histochemical methods it has been shown that the noradrenergic nerves in the jejunal villus are associated with the capillaries underlying the basolateral membrane of the epithelium. Noradrenergic fibres were also seen to lie between the epithelial basolateral membrane and the capillaries but were never observed close to the ...

The Sympathetic Innervation of the Human Foot
Plastic and Reconstructive Surgery, 2012The sympathetic innervation of the hand was demonstrated using formaldehyde staining techniques in the 1990s and provides a basis for both medical (botulinum toxin type A) and surgical (sympathectomy) therapeutic approaches. This research investigates the sympathetic innervation of the human foot using tyrosine hydroxylase immunohistochemistry.With ...

Sympathetic innervation-mediating protein
Neuroscience Research Supplements, 1990The present study was performed to elucidate the mechanisms and molecular basis of specific innervation of the peripheral tissues. Chick sympathetic nerve fibers densely innervate expansor secundariorum muscle, but not skeletal muscle. When a sympathetic ganglion was cultured in collagen gel with muscle explants, the ganglion extended neurites towards ...

Sympathetic Innervation of the Urethral Muscle in Cattle
Zentralblatt für Veterinärmedizin Reihe A, 1985SummaryThe possible existence and types of sympathetic innervation of the urethral muscle in cattle were investigated in vitro by pharmacological stimulation and blockage of alpha and beta adrenergic receptors with agonist and antagonist drugs. The contractile action was mediated by adrenergic receptors of alpha‐1 type, while relaxation was obtained by

Sympathetic innervation of the ileocecal junction in horses
Journal of Comparative Neurology, 2010AbstractThe distribution and chemical phenotypes of sympathetic and dorsal root ganglion (DRG) neurons innervating the equine ileocecal junction (ICJ) were studied by combining retrograde tracing and immunohistochemistry. Immunoreactivity (IR) for tyrosine hydroxylase (TH), dopamine beta‐hydroxylase (DBH), neuronal nitric oxide synthase (nNOS ...

Innervation of the spinal cord by sympathetic fibers
Experimental Neurology, 1980Abstract Pharmacologic and neurochemical studies suggest that catecholamines are still present below the level of transection in the spinal cord of the chronic spinal animal, despite the degeneration of bulbospinal catecholamine pathways. Histofluorescence studies of rat and dog spinal cord revealed noradrenergic fibers and varicosities remaining in ...
