As already pointed out, the cell membrane is the plasma membrane surrounding the cell. The term“plasma membrane”also includes the biological membranes that form the outer boundary of the internal compartments (organelles). (Ref. 1) Thus, strictly speaking, the plasma membrane is a more wide-r...

Structure of the Plasma Membrane Structure of the Plasma Membrane The phosphate group greatly alters the lipid because the phosphate group is polar. The phospholipid bilayer forms a barrier that is polar on the surface and nonpolar in the middle. The polar group allows the cell membrane to intera...
cell membrane,cytomembrane cell- (biology) the basic structural and functional unit of all organisms; they may exist as independent units of life (as in monads) or may form colonies or tissues as in higher plants and animals semipermeable membrane- a membrane (as a cell membrane) that allows...
Volume 3 continues the approach carried out in the first two volumes of this se ries of publishing articles on membrane methodology which include, in addition to procedural details, incisive discussions of the ap plications of the methods and of their limitations. Wh at is the theoretical basis...
When I took biology I was totally fascinated by the plasma membrane. It really is integral to the cells functioning because of the way it allows some things, but not others, to pass through the membrane. There are also membranes inside the cell. In fact, the compartmentalization inside the ...
Through such membrane interactions, it is well accepted that IFs play important roles in the establishment and maintenance of tissue integrity. However, by organizing cell-surface complexes, IFs likely regulate, albeit indirectly, signaling pathways that are key to tissue homeostasis and repair...
Plasma membrane integrity is essential for cellular homeostasis. In vivo, cells experience plasma membrane damage from a multitude of stressors in the extra- and intra-cellular environment. To avoid lethal consequences, cells are equipped with repair pat
