Innervation of the cat ureter. An experimental study. 1981

E Fehér, and N B Salimova, and D A Sakharov, and J Vajda

Innervation of the ureter was studied by fluorescent microscopy using glyoxylic methods and by electron microscopy in the normal state and after extirpation of hypogastric ganglia. According to the morphology of the vesicle population, four groups of nerve processes could be distinguished: Type a with a dominant population of small agranular vesicles; Type b with a large number of small granular vesicles; Type c with 80 to 120 nm granulated vesicles; Type d with large 150 to 250 nm neurosecretory vesicles. After extirpation of the hypogastric ganglia, degenerated nerve terminals could be found in all the layers of the ureter, but a few fluorescent fibres could be observed in the muscle layers, too. It is assumed that most of the fluorescent fibres originate from the hypogastric ganglia and the others from the local neurons of from the spinal ganglia. These nerve processes act directly on the smooth muscle cells.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D008856	Microscopy, Fluorescence	Microscopy of specimens stained with fluorescent dye (usually fluorescein isothiocyanate) or of naturally fluorescent materials, which emit light when exposed to ultraviolet or blue light. Immunofluorescence microscopy utilizes antibodies that are labeled with fluorescent dye.

D009412	Nerve Fibers	Slender processes of NEURONS, including the AXONS and their glial envelopes (MYELIN SHEATH). Nerve fibers conduct nerve impulses to and from the CENTRAL NERVOUS SYSTEM.	Cerebellar Mossy Fibers,Mossy Fibers, Cerebellar,Cerebellar Mossy Fiber,Mossy Fiber, Cerebellar,Nerve Fiber
D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
