Cytoplasm form a fenestrated epithelium around the fenestrated capillaries of the glomerulus. PubMed Barry Brenner capillary loop – C stage The third stage in nephron development between weeks. Nephron Functional unit of kidney Humans up to 1 million Filtration of waste from blood Endocrine Blood pressure regulation.

Named in after Sir William Bowman — an English surgeon and anatomist. Mucosa – mucus layer a transitional epithelium layer formed into urogenitql rugae.

In females, these degenerate. The outer layer is the parietal layer.

Renal System Histology

Named after Caspar Friedrich Wolffa German scientist and early embryology researcher and is said to have established the doctrine of germ layers. The muscular layer has also been hiatologi as being subdivided into 3 fibre layers: In humans, the urethral length differs between the sexes male longer, female shorter. Normally the majority of nephrogenic rests either regress or become dormant.

A few mesonephric tubules remain as efferent ductules histoloti the male and vestigial remnants in the female. Wilm’s tumour Bowman’s capsule – capsula glomeruli, glomerular capsule Surrounds the glomerulus within the nephron with a vascular and urinary pole and is the beginning of the tubular component. V – S – C – M urinary – Term used to describe all components of the kidney system including the bladder, ureters and urethra.


On the outside of the capillary, the foot processes FP cover a major part of the glomerular basement membrane GBM circumference. The intermediate mesonephros develops and disappears with the exception of its duct, the mesonephric ductwhich will form the male reproductive duct system.

Serous – the superior or abdominal surfaces and the lateral” surfaces of the bladder are covered by visceral peritoneum, the serous membrane serosa of the abdominal cavity, consisting of mesthelium and elastic fibrous connective tissue.

Submucosa – connects the muscular layer with the mucous layer. Discussion View source History. Capsule outer layer – dense CT fibroblasts and collagen inner layer – myofibroblasts.

Mouse renal podocyte EM [1]. V – S – C – M mesangial cells – Cells in the nephron glomerulus that form the connective tissue giving structural support to podocytes and vessels. The endothelial cell coats the inner surface of the capillary wall and is followed by the three layers of the glomerular basement membrane GBM.


Hisfologi – S – C – M transitional epithelium – urothelium Histological term to describe the epithelium lining the ureters and urinary bladder.

This section of notes gives an overview mainly of adult renal histology, see also Renal System Development notes. It is rapidly replaced by the mesonephros, intermediate stage kidney, differentiating in mesoderm beneath.

Can be described anatomically by its 4 layers from inside outward: This forms the kidney of primitive fish and lower vertebrates. Kidney development occurs within the intermediate mesoderm interacting with endoderm. Renal System Histology From Embryology. Anatomically can be described in two parts the abdominal part pars abdominalis and pelvic part pars pelvina. Region also in close contact with the efferent and afferent arterioles of the glomerulus and involved in sodium chloride regulation.

This page was last modified on 30 Augustat Podocytes form the visceral layer of Bowman’s capsule and are at the filtration barrier between capillary blood and the nephron tubular system and function to ultrafiltrate blood, and support glomerular capillary pressures.
