Related to Bowman capsule: nephron, loop of Henle, Proximal convoluted tubule

glo·mer·u·lar cap·sule

[TA]
the expanded beginning of a nephron composed of inner and outer layers: the visceral layer consists of podocytes that surround a tuft of capillaries (glomerulus); the parietal layer is simple squamous epithelium that becomes cuboid at the tubular pole.

glo·mer·u·lus

, pl. glomeruli (glō-meryū-lŭs, -lī)
1. A plexus of capillaries.
2. A tuft formed of capillary loops at the beginning of each nephric tubule in the kidney; this tuft with its capsule constitutes the renal corpusculum (malpighian body).
3. The twisted secretory portion of a sweat gland.
4. A cluster of dendritic ramifications and axon terminals forming a complex synaptic relationship and surrounded by a glial sheath.
Synonym(s): Bowman capsule, glomerule.

Electron microscopy demonstrates the presence of subendothelial or mesangial immune deposits in type-I MPGN and dense-black, intramembranous, ribbonlike deposits in the GBMs, Bowman capsules, and tubular basement membranes in the type-II form of MPGN (Figure 5).
We define periglomerular fibrosis as glomeruli with open capillaries, but lamellated, frequently wrinkled, Bowman capsular basement membrane and circumferential layers of interstitial-type collagen around, within, or between the usually thickened, frequently lamellated, Bowman capsule basement membrane (Figure 2).
X-linked heterozygotes show a discontinuous or mosaic pattern, with alternating positive and negative staining areas of the GBM and of Bowman capsule (Figure 4, B).
These glomeruli also had periglomerular fibrosis in and around the Bowman capsule but no evidence of segmental sclerosis of the glomerular capillary tufts.
