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. 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.

If the link no longer works search the web with the link text or name. Muscular – the detrusor muscle is the muscle of the urinary bladder wall.

Named in after Sir William Bowman — an English surgeon and anatomist. They develop from the ureteric bud and are lined by a transitional epithelium with an outer muscular wall.

Mouse renal podocyte EM [1]. Moodle – Virtual Slides requires Moodle log in. V – S – C – M urinary – Term used to describe all components of the kidney system including the bladder, ureters and urethra.


Renal System Histology – Embryology

Submucosa – connects the muscular layer with the mucous layer. In humans, the urethral length differs between the sexes male longer, female shorter. Privacy policy About Embryology Disclaimers. V – S – C – M diabetes insipidus – The disorder is related to the hormone antidiuretic hormone ADH, also called vasopressin its synthesis, secretion, receptors and signaling pathway. Wt1 also required at early stages of gonadal development.

The muscular layer has also been described as being subdivided into 3 fibre layers: V – S – C – M transitional epithelium – urothelium Histological term to describe the epithelium lining the ureters and urinary bladder. The inner layer is the visceral layer.

The adult ureter is a thick-walled muscular tube, 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 and involved in sodium chloride regulation. This page was last modified on 30 Augustat The intermediate mesonephros develops and disappears with the histoloti of its duct, the mesonephric ductwhich will form the male reproductive duct system.

The differentiation of podocytes involves the formation of cellular foot processes and then the slit membrane.

Kidney development occurs within the intermediate mesoderm interacting with endoderm. This forms the kidney of primitive fish and lower vertebrates.

Named after Caspar Friedrich Wolffa German scientist and early embryology researcher and is said to have established the doctrine of germ layers. V – S – C – M mesangial cells – Cells in the nephron urogenitxl that form the connective tissue giving structural support to podocytes and vessels. The slit-diaphram can be discerned in between the foot processs.


The outer layer is the parietal layer. In humans, this very rudimentary kidney forms very early at the level of the neck. Normally the majority of nephrogenic rests either regress or become dormant.

Renal System Histology

Nephron Functional unit of kidney Humans up to 1 million Filtration of waste from blood Endocrine Blood pressure regulation. Google Translate – select your language from the list shown below this will open a new external page.

In females, these degenerate. In females this duct degenerates some remnants may remain associated in broad ligament. Yistologi Embryology is provided as an educational resource with no clinical information or commercial affiliation.

It is rapidly replaced by the mesonephros, intermediate stage kidney, differentiating in mesoderm beneath. Anatomically can be described in two parts the abdominal part pars abdominalis and pelvic part pars pelvina.

In males, the mesonephric tubules go on to form the ducts of the testis. The rests are further characterised by the time of generation leading to different anatomical kidney locations:
