Nephron Functional unit of kidney Humans up to 1 million Filtration of waste from blood Endocrine Blood pressure regulation. On the outside of the capillary, the foot processes FP cover a major part of the glomerular basement membrane GBM circumference. V – S – C – M mesangial cells – Cells in the nephron glomerulus that form the urogeniyal tissue giving structural support to podocytes and vessels.
External Links Notice – The dynamic nature of the internet may mean that some of these listed links may no longer function. These neoplastic rests can develop postnatally as a benign form adenomatous rest or a malignant Wilm’s tumour form.
A few mesonephric tubules remain as efferent ductules in the male and vestigial remnants in urofenital female. Anatomically can be described in two parts the abdominal part pars abdominalis and pelvic part pars pelvina. V – S – C – M urinary – Term used to describe all components of the kidney system including the hkstologi, ureters and urethra.
V – S – C – M transitional epithelium – urothelium Histological term to describe the epithelium lining the ureters and urinary bladder. The ureter is composed of three layers: Capsule outer layer – dense CT fibroblasts and collagen inner layer – myofibroblasts.
It is rapidly replaced by the mesonephros, intermediate stage kidney, differentiating in mesoderm beneath. Named in after Sir William Bowman — an English surgeon and anatomist. Wt1 urogebital required at early stages of gonadal development.
The inner layer is the visceral layer. Mouse renal podocyte EM .
If the link no longer works search the web with the yrogenital text or name. 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.
In males, the mesonephric tubules go on to form the ducts of the testis. UNSW Embryology is provided as an educational resource with no clinical information or commercial affiliation. Google Translate – select your language urogenita the list shown below this will open a new external page. This forms the kidney of primitive fish and lower vertebrates.
Kidney development occurs within the intermediate mesoderm interacting with endoderm.
Muscular – the detrusor muscle is the muscle of the urinary bladder wall. The slit-diaphram can be discerned in between the foot processs.

Renal System Histology – Embryology
Discussion View source History. Region also in close contact with the efferent and afferent arterioles of the glomerulus and involved in sodium chloride regulation.
This section of notes gives an overview mainly of adult renal histology, see also Renal System Development notes. In humans, the urethral length differs between the sexes male urogfnital, female shorter.
Renal System Histology From Embryology. They develop from the ureteric bud and are lined by a transitional epithelium with an outer muscular wall. Normally the majority of nephrogenic rests either regress or become dormant.
Can be described anatomically by its 4 layers from inside outward: The outer histologgi is the parietal layer.
Renal System Histology
Detrusor Muscle The adult detrusor muscle consists of three layers of smooth involuntary muscle fibres. The intermediate mesonephros develops and disappears with the exception of its duct, the mesonephric ductwhich will form the male reproductive duct system.
PubMed Barry Brenner capillary loop – C stage The third stage in nephron development between weeks. Note that while the smooth muscle fibre layer organisation is described as longitudinal or histooogi, this is only a general organisation of fibre direction, and is better described as a “spiral” organisation. The muscular layer has also been described as being subdivided into 3 fibre layers: 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.
Named after Caspar Friedrich Wolffa German scientist and early embryology researcher and is said to have established the doctrine of germ layers. Transmission electron micrscopy of a mouse glomerular capillary revealing the structural composition of the glomerulus.
Mucosa – mucus layer a transitional epithelium layer formed into folds rugae. Moodle – Virtual Slides requires Moodle log in. In females yistologi duct degenerates some remnants may remain associated in broad ligament. This leads to a grossly dilated renal pelvis causing extensive renal damage before birth.
Cytoplasm form a fenestrated epithelium around the fenestrated capillaries of the glomerulus. The differentiation of podocytes involves the formation of cellular foot processes and then the slit membrane.
In humans, this very rudimentary kidney forms very early at the level of the neck. In females, these degenerate.
