| Abstract | ||
| The house mice kidneys lay on each side of the upper lumbar vertebra in the abdominal cavity behind the peritoneum. The right kidney was situated more cranially than the left. The shape of two kidneyswas bean like structure. The mean weight of the right kidney was 0.076±0.013gm while, the left kidney was 0.072±0.011gm. The mean length, width and thickness of the right kidneys were 7.4±0.647mm, 5.098±0.427mm, 3.624±0.198mm respectively while those of the left were 6.8±0.518mm, 4.768±0.481mm, 3.468±0.123mmrespectively. The kidneys consist of two distinct regions, the outer cortex is reddish brown in color and inner medulla, and both terminate bysingle elongated renal papillae. The house mice kidneys were covered by a thin dense connective tissue capsule with adipose tissue. The nephron composed of large and small rounded or irregular renal corpuscle; each The renal corpuscle is forms the glomeruli that enveloped by Bowman’s capsule, and the proximal convoluted tubules, loop of Henle and the distal convoluted tubules. The cortex consists from renal corpuscles, proximal convoluted tubules and distal convoluted tubules. The proximal convoluted tubule arises from the parietal epithelium of Bowman’s capsule of the urinary pole of the renal corpuscle lined by simple high cuboidal epithelium. The distal convoluted tubules were lined by simple low cuboidal epithelium. The part of the distal convoluted tubule in contact with glomerular root has the macula densa. The medulla of each kidney is formed from thick parts lined bysimple cuboidal epithelium and thin parts of the loops of Henle lined by simple squamous epithelium and the thin limb had a distinct rounded lumen and collecting tubules are lined by pale cuboidal epithelium with rounded nuclei and MJPS….Vol.(2)….No(1)….December 2014 basophilic cytoplasm. The terminal portion of these tubules is lined by columnar epithelium and is called papillary ducts. | ||
