membranes, plural;
  1. A pliable sheetlike structure acting as a boundary, lining, or partition in an organism

  2. A thin pliable sheet or skin of various kinds
    • - the concrete should include a membrane to prevent water seepage
  3. A microscopic double layer of lipids and proteins that bounds cells and organelles and forms structures within cells


  1. a thin pliable sheet of material
  2. a pliable sheet of tissue that covers or lines or connects the organs or cells of animals or plants
  3. A biological membrane or biomembrane is an enclosing or separating membrane that acts as a selective barrier, within or around a cell. It consist of a lipid bilayer with embedded proteins that may constitute close to 50% of membrane content. . ...
  4. In theoretical physics, a membrane, brane, or p-brane is a spatially extended mathematical concept that appears in string theory and its relatives (M-theory and brane cosmology) that exists in a static number of dimensions.
  5. A membrane is a layer of material which serves as a selective barrier between two phases and remains impermeable to specific particles, molecules, or substances when exposed to the action of a driving force. ...
  6. (The Membranes) The Membranes were a post-punk band formed in Blackpool, Lancashire in 1977, the initial line-up being John Robb (bass guitar), Mark Tilton (guitar), Martin Critchley (vocals) and Martin Kelly (drums). ...
  7. A flexible enclosing or separating tissue forming a plane or film and separating two environments (usually in a plant or animal); A mechanical, thin, flat flexible part that can deform or vibrate when excited by an external force; A flexible or semi-flexible covering or waterproofing whose ...
  8. (membranes) The amnion and chorion, which make up the amniotic sac
  9. (Membranes) (in CCS)  Thin sheets of material that can separate carbon dioxide from other gases – acts like a sieve
  10. (Membranes) are soft, pliable sheets or layers that can be used in filtration processes.  Membrane Bioreactors combine activated sludge treatment processes and membrane filtration equipment to separate liquids and solids.
  11. (membranes) The sac or "bag of waters" filled with amniotic fluid in which the developing baby grows. The "membranes" which make up the sac may occasionally rupture naturally as labour begins, but usually remain intact until the end of the first stage of labour. ...
  12. Membranes are thin films made with structures designed to provide selective transport of solutes.  In general, the selectivity of a membrane is based on its ability to pass or exclude species according to their size.  Membrane structures may become homogeneous or asymmetric. ...
  13. Mucous membranes line a body cavity that opens directly to the exterior, preventing the cavity from drying out e.g. in the mouth. Serous membranes line a body cavity that does not directly open to the outside, and provide lubrication so that organs can move more easily e.g. ...
  14. A generic term relating to a variety of sheet goods used for certain built-up roofing repairs and application.
  15. a flexible or semi-flexible roof covering or waterproofing layer, whose primary function is the exclusion of water.
  16. The portion of the roofing system that serves as the waterproofing material. Can be composed of one material or several materials laminated together.
  17. A thin sheet or surface film, either natural or man-made of microporous structure that performs as an effluent filter of particles down to the size range of chemical molecules and ions. Such membranes are termed "semipermeable" because some substances will pass through but others will not.
  18. A very thin layer of tissue that covers a surface.
  19. Thin layer of tissue or material, usually an outer layer or lining of organs or group of organs.
  20. A membrane is a thin wall or film that allows only some substances to pass through it or that prevents the mixing of two substances.
  21. Thin, flexible film of proteins and lipids that encloses the contents of a cell; it controls the substances that go into and come out of the cell. Also, a thin layer of tissue that covers the surface or lines the cavity of an organ.
  22. A microporous structure that acts as a highly efficient filter that allows passage of water, but rejects suspended solids and colloidals; depending on membrane type, ions and small molecules might or might not be rejected.
  23. A membrane or sheet or thin zone or facing, made of a flexible impervious material such as asphaltic concrete, plastic concrete, steel, wood, copper, plastic, etc. A cutoff wall or core wall, if thin and flexible, is sometimes referred to as a "diaphragm wall."
  24. A flexible layer surrounding a cell, organelle (such as the nucleus), or other bodily structure. The movement of molecules across a membrane is strictly regulated in both directions.
  25. (MEM-brayn) — Tissue that connects the amniotic sac to the uterus.
