| fibroelastic membrane of larynx | A layer of fibrous and elastic fibres, taking the place of the submucosa in the larynx. It is divided by the laryngeal ventricle into two parts: the quadrangular membrane superiorly and the conus elasticus inferiorly. Synonym: membrana fibroelastica laryngis. (05 Mar 2000) |

| urogenital membrane | The ventral portion of the embryonic cloacal membrane after its division by the urorectal septum. (05 Mar 2000) |
| fibrous membrane | The outer fibrous part of the capsule of a synovial joint, which may in places be thickened to form capsular ligaments. Synonym: membrana fibrosa, stratum fibrosum, fibrous membrane. (05 Mar 2000) |
| urorectal membrane | In the embryo, urorectal septum separating the cloaca into urogenital sinus and rectum. Synonym: urorectal fold. (05 Mar 2000) |
| Fielding's membrane | 1. <cell biology> Layer of reflective tissue just behind the pigmented retinal epithelium of many vertebrate eyes. May consist either of a layer of guanine crystals or a layer of connective tissue. In bovine eyes reflects a blue green iridescent colour. 2. <plant biology> Layer of cells in the sporangium of a vascular plant that nourishes the developing spores. (18 Nov 1997) |
| uteroepichorial membrane | Rarely used term for decidua parietalis. (05 Mar 2000) |
| flaccid membrane | Triangular loose part of tympanic membrane between the malleolar folds. Synonym: pars flaccida membranae tympani, flaccid membrane, membrana flaccida, Rivinus' membrane, Shrapnell's membrane. (05 Mar 2000) |
| flaccid part of tympanic membrane | Triangular loose part of tympanic membrane between the malleolar folds. Synonym: pars flaccida membranae tympani, flaccid membrane, membrana flaccida, Rivinus' membrane, Shrapnell's membrane. (05 Mar 2000) |
| foetal membrane | A structure or tissue that develops from the fertilised ovum but does not form part of the embryo proper. Synonym: embryonic membrane, extraembryonic membrane. (05 Mar 2000) |
| limbus of tympanic membrane | Margin of the tympanic membrane attaching to the tympanic sulcus. Synonym: limbus membranae tympani. (05 Mar 2000) |

| lysosome associated membrane glycoprotein | <protein> Lysosome specific integral membrane glycoproteins. Long luminal domain, short transmembrane domain, very short cytoplasmic tail. Function not yet clear. (18 Nov 1997) |
| acetoacetyl-acyl carrier protein synthase | <enzyme> E coli enzyme, that catalyses condensation of malonyl-acyl carrier protein plus acetyl-acyl carrier protein; not inhibited by cerulenin Registry number: EC 2.3.1.- Synonym: acetoacetyl-acp synthase (26 Jun 1999) |
| acid soluble spore protein | <molecular biology> A DNA binding protein in the spores of some bacteria, thought to stabilise the DNA in an A configuration, so protecting it from cleavage by enzymes or UV light. (18 Nov 1997) |
| acute-phase protein | <haematology> These plasma proteins (in addition to fibrinogen) increase 25% or more in response to inflammation and injury are under direct control of interleukin-6 (IL-6) (hepatocyte-stimulating factor). Other proteins which increase are ceruloplasmin, C3 and C4 which increase 50% or more; alpha-1 acid glycoprotein, alpha-1 antitrypsin, haptoglobin and fibrinogen (the major determinant of viscosity 1 ) which increase two- to fourfold; C-reactive protein (CRP) and serum amyloid A which increase several hundred-fold. Despite long-held clinical opinion to the contrary, available data indicate that neither ESR nor measurement of specific acute-phase reactants are useful in excluding underlying infection or inflammation regardless of the pretest probability. These proteins are secreted into the blood in increased or decreased quantities by hepatocytes in response to trauma, inflammation, or disease. They can serve as inhibitors or mediators of the inflammatory processes. Certain acute-phase proteins have been used to diagnose and follow the course of diseases or as tumour markers.
