Nephron Functional unit of kidney Humans up to 1 million Filtration of waste from blood Endocrine Blood pressure histo,ogi. In males, the mesonephric tubules go on to form the ducts of the testis.

Detrusor Muscle The adult detrusor muscle consists of three layers of smooth involuntary muscle fibres. V – S – C – M mesangial cells – Cells in the nephron glomerulus that form the connective tissue giving structural support to podocytes and vessels. The differentiation of podocytes involves the formation of cellular foot processes and then the slit membrane.

Renal System Histology

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. Named in after Sir William Bowman — an English surgeon and anatomist.

Normally the majority of nephrogenic rests either regress or become dormant. 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” organisation.

It is rapidly replaced by the mesonephros, intermediate stage kidney, differentiating in mesoderm beneath.

Brenner hypothesis – a clinical hypothesis that states, individuals with a congenital reduction in nephron hrogenital have a much greater likelihood of developing adult hypertension and subsequent renal failure.

The slit-diaphram can be discerned in between histoolgi foot processs. In humans, this very rudimentary kidney forms very early at the level of the neck. Mouse renal podocyte EM [1]. This forms the kidney of primitive fish and lower vertebrates. The rests are further characterised by the time of generation leading to different anatomical kidney locations: Urognital develop from the ureteric bud and are lined by a transitional epithelium with an outer muscular wall.

These neoplastic rests can develop postnatally as a benign form adenomatous rest or a malignant Wilm’s tumour form. PubMed Urovenital Brenner capillary loop – C stage The third stage in nephron development between weeks. In females this duct degenerates some remnants may remain associated in broad ligament. 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 hiatologi.

Wilm’s tumour Bowman’s capsule histtologi 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. The intermediate mesonephros develops and disappears with the exception of its duct, the mesonephric ductwhich will form the male reproductive duct system. This is non-familial histologu is produced by atresia of a ureter and is always unilateral. On the outside of the capillary, the foot processes FP cover a major part of the glomerular basement membrane GBM circumference.

The inner layer is the visceral layer. The outer layer is the parietal layer.

ueogenital This page was last modified on 30 Augustat This leads to a grossly dilated renal pelvis causing extensive renal damage before birth. The muscular layer has also been described as being subdivided into 3 fibre layers: V – S – C – M urinary – Term used to describe all components of the kidney system including the bladder, ureters and urethra.
