| 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) |
| 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) |
| 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) |
