| 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) |

| bowman | A man who uses a bow; an archer. "The whole city shall flee for the noise of the horsemen and bowmen." (Jer. Iv. 29) Bowman's root. <botany> See Indian physic, under Indian. Source: Websters Dictionary (01 Mar 1998) |

| Bowman-Birk inhibitor | A polypeptide that will inhibit both trypsin and chymotrypsin. (05 Mar 2000) |
| 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, Sir William | <person> B. Nantwich, Cheshire, July 20th, 1816. Was a Surgeon and Anatomist. Was Surgeon to Birmingham General Hospital and went to London in 1837. Was elected F.R.S. (1841) and F.R.C.S. (1854) and was appointed Professor of Anatomy and Physiology at King's College, London (1848-1956). Was the leading Opthalmic Surgeon in England. D. At his house, Joldwynds, near Dorking, Mar. 29th, 1892. Bowman's Capsule - surrounding the glomerulus in the kidney. Bowman's Glands - glands in the olfactory mucous membrane. On the structure and use of the Malpighian bodies of the kidney. Phil Trans. 1842. Much of Bowman's best anatomical work is to be found in Robert Todd's Cyclopaedia of Anatomy and Physiology. London 1835-1859. Lived: 1816-1892. (05 Dec 1998) |
| 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) |
| trypsin inhibitor, bowman-birk soybean | <chemical> A low-molecular-weight protein (minimum molecular weight 8000) which has the ability to inhibit trypsin as well as chymotrypsin at independent binding sites. It is characterised by a high cystine content and the absence of glycine. Pharmacological action: trypsin inhibitors. (12 Dec 1998) |
| Abbe theory of image formation | <optics, physics> Abbe's theory is based on the fact that a non-self-luminous particle, which is illuminated by an extraneous source, gives rise to diffracted light rays, in addition to the dioptric pencil. He stated that to form a good microscopical image as many of the diffracted rays as possible should be intercepted by the objective. With closely ruled lines, his theory is easily demonstrated by observing the back lens of the objective, for here the diffracted rays can be observed directly if the aperture diaphragm is closed. It can be shown that, when the illumination is arranged to exclude the diffracted images, resolution is lost. (11 Mar 1998) |
| adsorption theory of narcosis | That a drug becomes concentrated at the surface of the cell as a result of adsorption, and thus alters permeability and metabolism. (05 Mar 2000) |
| Altmann's theory | A theory that protoplasm consists of granular particles (called bioblasts) that are clustered and enclosed in indifferent matter. (05 Mar 2000) |
