Glomerular capillaries have small pores in their walls, just like a very fine mesh sieve. The glomerulus is a cluster of capillary loops enclosed by Bowman's capsule, which is part of the renal tubule. Bowman's capsule has two layers: The visceral layer is in contact with the glormerulus, and is composed of specialized epithelial cells known as podocytes. This is a normal glomerulus by light microscopy. The glomerular capillary loops are thin and delicate. Endothelial and mesangial cells are normal in number. The surrounding tubules are normal.

Glomeruli can be located in the cortex of the kidney or the corticomedullary junction. Blood that is traveling through the capillary loops is selectively filtered across the glomerular filtration barrier to form an ultrafiltrate of the plasma. 2019-01-04 · We begin with normal histology of the kidney and specifically the glomerulus or renal corpuscle. After all, one needs to know what is normal before learning to recognize abnormalities. Distinguishing between normal and abnormal is not always easy. 2021-02-23 · Learning about kidney histology doesn’t have to be as painful as kidney stones! We have composed a simple step-by-step guide to help you master this complicated yet fascinating organ.

This is where ultrafiltration of blood occurs, the first step in urine production. The filtration barrier consists of 3 components: Endothelial cells of glomerular capillaries Histology @ Yale Slide List The filtration barrier of the glomerulus consists of a fenestrated capillary epithelium with a negatively charged surface that repels many plasma proteins.

Blood that is traveling through the capillary loops is selectively filtered across the glomerular filtration barrier to … glomerulus: A small, intertwined group of capillaries within the nephrons of the kidney that filter the blood to make urine. A Nephron A nephron is the basic structural and functional unit of the kidneys that regulates water and soluble substances in the blood by filtering the blood, reabsorbing what is needed, and excreting the rest as urine. Normal Histology and Important Histo-anatomic Structures .

In the kidney, the basal lamina acts as a molecular filter.At the neuromuscular junction, the basal lamina that surrounds the muscle cells, separates the nerve cell from the muscle cell at the synapse, and helps to regenerate the synapse after injury, and helps to localise acetylcholine receptors.

Blood flow autoregulates across the filtration capillaries (glomeruli) due to the unique arrangement of blood vessels. The glomerulus, in contrast to the majority of other capillary beds, sits between two arterioles; receiving blood supply from the upstream afferent arteriole, and blood exiting downstream via the efferent arterioles (E for exit).

Each nephron is composed of a glomerulus and tubule. The glomerulus acts to filter the blood free of cells and large proteins, producing an ultrafiltrate composed of the other smaller circulating elements. Immune-mediated injury to the glomerulus typically arises from the deposition of antibodies within the glomerulus, a process which can occur via a variety of distinct mechanisms as described individually below. Whatever the mechanism, the presence of antibodies within the glomerulus results in a final common pathway of immune-mediated injury.

This trichrome stain of a glomerulus in a patient with focal segmental glomerulosclerosis (FSGS) demonstrates blue collagen deposition. FSGS accounts for about a sixth of cases of nephrotic syndrome in adults and in children. FSGS is most often a primary disease, but it can be secondary to other conditions.
