[17] [6] [18] Differences in kidney structure are the result of adaptations during evolution to variations in body mass and habitats (in particular, aridity) between species. [ 19 ] [ 20 ] [ 12 ] The cortex and medulla of the kidney contain nephrons , [ 21 ] each of which consists of a glomerulus and a complex tubular system. [ 22 ]
The mesonephros in reptiles functions for some time after birth simultaneously with the metanephros, while later the metanephric kidneys become permanent and the mesonephros degenerates. [ 38 ] The kidneys in reptiles are located mainly in the caudal part (away from the head) of the abdominal cavity [ 49 ] [ 50 ] or retroperitoneally (behind ...
Metanephric adenoma (MA) is a rare, benign tumour of the kidney, that can have a microscopic appearance similar to a nephroblastoma (Wilms tumours), [1] or a papillary renal cell carcinoma. It should not be confused with the pathologically unrelated, yet similar sounding, mesonephric adenoma .
Mass movement of sodium occurs through the cells, by secondary active transport on the apical membrane, followed by active resorption across the basolateral membrane via the Na + /K +-ATPase. [10] The solutes are absorbed isotonically , in that the osmotic potential of the fluid leaving the proximal tubule is the same as that of the initial ...
Metanephric dysplastic hematoma of the sacral region (MDHSR) has been described by Cozzutto and Lazzaroni-Fossati in 1980, [1] by Posalaki et al. in 1981 [2] and by Cozzutto et al. in 1982. [3] Three additional cases were seen by Finegold.
The RENAL Nephrometry Scoring System is used to measure the complexity of kidney tumors for determining whether a renal mass is appropriate for partial or radical nephrectomy, and is estimated by CT scan as follows: [7] The nephrometery score takes into account the size of the tumor (Radius), how much of the tumor is inside or outside of the ...
During early development (approximately day 22 in humans), the pronephric duct forms from the intermediate mesoderm, ventral to the anterior somites. The cells of the pronephric duct migrate caudally whilst inducing adjacent mesenchyme to form the tubules of the initial kidney-like structure called the pronephros. [6]
