Mucosa – mucus layer a transitional epithelium layer formed into folds rugae. Wt1 also required at early stages of gonadal development.

The endothelial cell coats the inner surface of the capillary wall and is followed by the three layers of the glomerular basement membrane GBM. Note that while the smooth muscle fibre layer organisation is described as longitudinal or circular, this is only a general organisation of fibre direction, and is better described as a “spiral” urogenitl. 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.

Privacy policy About Embryology Disclaimers. Submucosa – connects the muscular layer with the mucous layer. The differentiation of podocytes involves the formation of cellular foot processes and then the slit membrane.

This forms the kidney of primitive fish and lower vertebrates. If the link no longer works search the web with the link text or name. Detrusor Muscle The adult detrusor muscle consists of three layers of histllogi involuntary muscle fibres. The slit-diaphram can be discerned in between the foot processs.

Renal System Histology

A few mesonephric tubules remain as efferent ductules in the male and vestigial remnants in the female. These neoplastic rests can develop postnatally as a benign form adenomatous rest or a malignant Wilm’s tumour form. The outer layer is the parietal layer.


In humans, this very rudimentary kidney forms very early at the level of the neck. They develop from the ureteric bud and are lined by a transitional epithelium with an outer muscular wall. Serous – the superior or abdominal surfaces and the lateral” surfaces of the bladder are covered by visceral urogenita, the serous membrane serosa of the abdominal cavity, consisting of mesthelium and elastic fibrous connective tissue.

In females this duct degenerates some remnants may remain associated in broad ligament. V – S – C – M transitional epithelium – urothelium Histological term to describe the epithelium lining the ureters and urinary bladder. In males, the mesonephric tubules go on to form the ducts of the testis.

Mouse renal podocyte EM [1]. The adult ureter is a thick-walled muscular histolpgi, 25 – 30 cm in length, running from the kidney to the urinary bladder. Region also in close contact with the efferent and afferent arterioles of the glomerulus urogenktal involved in sodium chloride regulation. Nephron Functional unit of kidney Humans up to 1 million Filtration of waste from blood Endocrine Blood pressure regulation.

V – S – C – M urinary – Term used to describe all components of the kidney system histologo the bladder, ureters and urethra. 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.

Google Translate – select your language from the list shown below this will open a new external page. This leads to a grossly dilated renal pelvis causing extensive renal damage before birth.

On the outside of the capillary, the foot processes FP cover a major part of the glomerular basement membrane GBM circumference. Anatomically can be described in two parts the abdominal part pars abdominalis and pelvic part pars pelvina. Transmission urogenjtal micrscopy of a mouse glomerular capillary revealing the structural composition of the glomerulus.

Capsule outer layer – dense CT fibroblasts and collagen inner layer – myofibroblasts. Cytoplasm form a fenestrated epithelium urigenital the fenestrated capillaries of the glomerulus.

This section of notes gives an overview mainly of adult renal histology, see also Renal System Development notes. The muscular layer has also been described as being subdivided into 3 fibre layers: The inner layer is the visceral layer.

This is non-familial and is produced by atresia of a ureter and is always unilateral. Named after Caspar Friedrich Wolffa German scientist and early embryology researcher and is said to have established the doctrine of germ layers. Can be described anatomically by its 4 layers from inside outward: UNSW Embryology is provided as an educational resource with no clinical information or commercial affiliation.

V – S – C – M mesangial cells – Cells in the nephron glomerulus that form the connective tissue giving structural support to podocytes and vessels. Moodle – Virtual Slides requires Moodle log in. Named in after Sir William Bowman — an English surgeon and anatomist.
