Research on sheep kidney histological structure

Abstract

Differential renal parenchyma into two distinct Areas: the cortex and medulla the. Cortical area is located in the external capsule, known as renal cortex is composed of: the narrow area adjacent to the renal capsule, called cortical area, corticis subcapsular or cortex; Called cortical area the labyrinth That is the cortical portion of the pyramids Ferrein; Bertin renal cortical columns That has extensions Between renal tissue is adjacent pyramids. The area contains cortical kidney renal corpuscles, distal convoluted tubules, proximal convoluted tubules. The area surrounded by the renal cortex is the medullary cortical areas and the layout of the pyramids Malpighi is uniform. The gap is made up of renal tissue rich in cells that CAN BE distinguished: fibroblasts, pericytes mononuclear bone marrow Located in the loops along the Henle, Vessels That supply. There is interstitial bone marrow Located in the cells Which is made up of cytoplasmic extensions That capillaries and tubules extend to the medulla. Located in Renal corpuscles have kidney and renal cortical columns HAVING relatively spheroidal aspect. Proximal tubule nuclei have unequal compared to distal tubule arrangement has Numerous nuclei, WILLING equidistant. Medullary conical or pyramidal area consists of structures with aspect Called renal pyramids or pyramids Malpighi targeted to the renal hilum top and the base is directed Towards the cortex. The base of each pyramid to start overtime Malpighi tubules just look Entering the renal cortex and has Ferrein Called pyramids. Cortical collecting tubules has papered of a simple cubic epithelium Which comprises two types of cells: clear cells that have the principal or many, have round nuclei and cells interspersed centrally located and dark, with cytoplasmic vesicles Numerous rare localized in the apical area. Medullary tubules collectors show columnar cell wall composed of small renal papilla cells and the level is high.
