Eight types of endocrine cells in the abomasum of sheep. 1983

Y Oomori

In the ovine abomasum, 8 types of endocrine cells were classified at ultrastructural level. The gastric-type EC cells contained oval and pleomorphic granules with high electron density. The intestinal-type EC cells were filled with oval, irregular and highly dense granules. ECL cells contained irregular granules with high density and wide clear spaces. D cells were filled with round granules showing low to moderate density and finely granular matrix D1 cells contained round or oval granules with variable, low to moderate density and finely granular content. G cells showed round and oval granules with moderate density, densely packed or flocculent content. F cells were filled with oval or elliptic granules showing low density with a finely granular and flocculent matrix. X cells contained round granules with high density and homogeneous material. Gastric-type EC cells, intestinal-type EC cells, D cells, and D1 cells were represented in the cardiac, fundic and pyloric gland areas of the ovine abomasum. ECL cells and F cells were confined to the fundic glands, G cells and X cells to the pyloric glands.

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

D000018	Abomasum	The fourth stomach of ruminating animals. It is also called the "true" stomach. It is an elongated pear-shaped sac lying on the floor of the abdomen, on the right-hand side, and roughly between the seventh and twelfth ribs. It leads to the beginning of the small intestine. (From Black's Veterinary Dictionary, 17th ed)	Abomasums
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.

D012756	Sheep	Any of the ruminant mammals with curved horns in the genus Ovis, family Bovidae. They possess lachrymal grooves and interdigital glands, which are absent in GOATS.	Ovis,Sheep, Dall,Dall Sheep,Ovis dalli
