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. Synonym(s): Bowman capsule, capsula glomeruli, malpighian capsule (1) , Müller capsuleglo·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. [Mod. L. dim. of L. glomus, a ball of yarn]Bowman, Sir William, English ophthalmologist, anatomist, and physiologist, 1816-1892.

Synonym(s): capsular spaceBowman strabismus scissorsBowman theory - that urine is formed by passive filtration through the glomeruli and secretion by the epithelium of the tubules.glo·mer·u·lus, pl. glomeruli (glō-meryū-lŭs, -lī) 1.
