Nephron Functional unit of kidney Humans up to 1 million Filtration of waste from blood Endocrine Blood pressure regulation. The differentiation of podocytes involves the formation of cellular foot processes and then the slit membrane.

These neoplastic rests can develop postnatally as a benign form adenomatous rest or a malignant Wilm’s tumour form.

The rests are further characterised by the time of generation leading to different anatomical kidney locations: The intermediate mesonephros develops and disappears with the exception of its duct, the mesonephric ductwhich will form the male reproductive duct system.

Region also in close contact with the efferent and afferent arterioles of the glomerulus hkstologi involved in sodium chloride regulation. In females this duct degenerates some remnants ugogenital remain associated in broad ligament. The muscular layer has also been described as being subdivided into 3 fibre layers: The inner layer is the visceral layer. V – S – C – M mesangial cells – Cells in the nephron glomerulus that form the connective tissue giving structural support to podocytes and vessels.

Wt1 also required at early stages of gonadal development. Capsule outer layer – dense CT fibroblasts and collagen inner layer – myofibroblasts. The outer layer is the parietal layer.

In humans, the urethral length differs between the sexes male longer, female shorter.

Privacy policy About Embryology Disclaimers. V – S – C – M transitional epithelium – urothelium Histological term to describe the epithelium lining the ureters and urinary bladder. This is non-familial and is produced by atresia of a ureter and is always unilateral.

Renal System Histology

This leads to a grossly dilated renal pelvis causing extensive renal damage before birth. Moodle – Virtual Slides requires Moodle log in. 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.

The slit-diaphram can be discerned in between the foot processs. Kidney development occurs within the intermediate mesoderm interacting with endoderm. The ureter is composed of three layers: Mucosa – mucus layer a transitional epithelium layer formed into folds rugae.

Can be described anatomically by its 4 layers from inside outward: Discussion View source History. In humans, this very rudimentary histplogi forms very early at the level of the neck.

It is rapidly replaced by the mesonephros, intermediate stage kidney, histolkgi in mesoderm beneath. V – S – C – M urinary – Term used to describe all components of the kidney system including the bladder, ureters and urethra.

Detrusor Muscle The adult detrusor muscle consists of three layers of smooth involuntary muscle fibres. Muscular – the detrusor muscle is the muscle of the urinary bladder wall.

This section of notes gives an overview mainly of adult renal histology, see also Renal System Development notes. PubMed Barry Brenner capillary loop – C stage The third stage in nephron development between weeks.

Renal System Histology – Embryology

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.

On the outside of the capillary, the foot processes FP cover a major part of the glomerular basement membrane GBM circumference. Brenner hypothesis – a clinical hypothesis that states, individuals with a congenital reduction in nephron number have a much greater likelihood of developing adult hypertension and subsequent renal failure. This page was last modified on 30 Augustat Normally the majority of nephrogenic rests either regress or become dormant.
