Bowman's capsule

[¦bō·mənz ′kap·səl]
(anatomy)
A two-layered membranous sac surrounding the glomerulus and constituting the closed end of a nephron in the kidneys of all higher vertebrates.

Bowman’s Capsule

 

(named after the 19th-century English physician W. Bowman), a cuplike cul-de-sac of the uriniferous tubule of the kidneys of vertebrate animals and humans. Bowman’s capsule surrounds the glomerulus and together they form the malpighian body. The wall of Bowman’s capsule consists of an inner and outer layer, between which is a gap—the cavity of Bowman’s capsule—lined with a flat epithelium. The inner layer adheres to the glomerulus, and the outer layer becomes the beginning of the uriniferous tubule. In Bowman’s capsule, so-called primary urine is formed.

The Bowman's capsule BM shows a significant increase of 8% in average thickness under diabetic conditions but only of 3% in EGb-protected animals without significant difference to the controls (Table 2).
Bowman's capsule. Bowman's capsule is made up of two cell layers: the visceral layer that forms the epithelial layer (podocytes) of the filtration barrier and the parietal cell layer that forms the outer layer of the capsule.
Fluid that is filtered through the glomerulus and into Bowman's capsule is labeled glomerular filtrate.
In respect to the Bowman's capsule, the mean values were 101,836.90 [micro][m.sup.3] in the control group and 145,824.35 [micro][m.sup.3] in the treated group, giving a p-value = 0.0015 also considered statistically significant.
Glomerulosclerosis, crescent formation, or adhesion to Bowman's capsules was observed in less than 10% of all biopsied glomeruli.
