| Bowman Birk protease inhibitors | <pharmacology> Family of serine protease inhibitors found in seeds of leguminous plants and cereals. (18 Nov 1997) |
| Bowman's capsule | The expanded beginning of a nephron composed of an inner and outer layer: the visceral layer consists of podocytes which surround a tuft of capillaries (glomerulus); the parietal layer is simple squamous epithelium which becomes cuboidal at the tubular pole. Synonym: capsula glomeruli, Bowman's capsule, malpighian capsule, Muller's capsule. (05 Mar 2000) |
| Bowman's disks | Disk's resulting from transverse segmentation of striated muscular fibre treated with weak acids, certain alkaline solutions, or freezing. (05 Mar 2000) |
| Bowman's gland | Branched tubuloalveolar serous secreting glands (of Bowman) in the mucous membrane of the olfactory region of the nasal cavity. Synonym: glandulae olfactoriae. (05 Mar 2000) |
| Bowman's membrane | A transparent homogeneous acellular layer, 6 to 9 um thick, lying between the basal lamina of the outer layer of stratified epithelium and the substantia propria of the cornea; considered to be a basement membrane. Synonym: lamina limitans anterior corneae, anterior elastic layer, Bowman's membrane, lamina elastica anterior, limiting layers of cornea. (05 Mar 2000) |
| Bowman's muscle | <anatomy> The smooth muscle of the ciliary body; it consists of circular fibres (Muller's muscle) and radiating fibres (meridional fibres, or Brucke's muscle); action, in contracting, its diameter is reduced (like a sphincter), reducing tensile (stretching) forces on lens, allowing it to thicken for near vision (accommodation). Synonym: musculus ciliaris, Bowman's muscle, ciliary ligament. (05 Mar 2000) |
| Bowman's probe | A double-ended probe for the lacrimal duct. (05 Mar 2000) |
| Bowman's space | The slitlike space between the visceral and parietal layers of the capsule of the renal corpuscle; it opens into the proximal tubule of the nephron at the neck of the tubule. Synonym: Bowman's space, filtration space. (05 Mar 2000) |
| Bowman's theory | That the urine is formed by passive filtration through the glomeruli and secretion by the epithelium of the tubules, the water and salts being separated from the plasma in the former situation, the urea and other urinary constituents in the latter. Parts of this theory are now known to be wrong. (05 Mar 2000) |
