| undulating membrane | Undulatory membrane, a locomotory organelle of certain flagellate (trypanosome and trichomonad) parasites, consisting of a finlike extension of the limiting membrane with the flagellar sheath; wavelike rippling of the undulating membrane produces a characteristic movement.

| Zinn's membrane | The anterior layer of the iris. (05 Mar 2000) |
| unit membrane | <cell biology> The three ply, approximately 7nm wide membrane structure found in all cells, composed of a fluid lipid bilayer with intercalated proteins. The unit membrane theory carries with it the presumption that all biological membranes have basically the same structure. (18 Nov 1997) |
| fenestrated membrane | An elastic membrane, as in elastic laminae of arteries. (05 Mar 2000) |
| fertilization membrane | A viscous membrane formed on the inner surface of the vitelline membrane from the cytoplasm of the egg cell after entry of the sperm, preventing the entry of additional sperm. (05 Mar 2000) |
| 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) |
