Plasma Membrane
All living cells, prokaryotic and eukaryotic, have a plasma membrane that encloses their contents and serves as a semi-porous barrier to the outside environment.
Plasma Membrane (Cell Membrane)
The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment.
Blood plasma is the liquid component of blood, in which the blood cells are suspended. It makes up about 55% of total blood volume.
Plasma Membrane
The plasma membrane surrounds the cell and functions as an interface between the living interior of the cell and the nonliving exterior.
All cells have one.
plasma membrane -- Outer membrane of a cell, sometimes called the cell membrane. The term plasma membrane is used more frequently when discussing prokaryotes.
plasma membrane
[Gk. plasma, form or mold + L. membrana, skin, parchment]
The membrane at the boundary of every cell that acts as a selective barrier, thereby regulating the cell's chemical composition.

Plasmalogens Phospholipids containing an α,β-unsaturated ether at the C-1 position of glycerol; abundant in phospholipids of the nervous system.
Mycoplasma
Walter Gilbert (Harvard University), a Nobel laureate who pioneered DNA sequencing in the mid-1970s, is leading efforts to sequence the genome of Mycoplasma capricolum.
mycoplasma. A member of the genus Mycoplasma. Mycoplasmas, unlike viruses, can reproduce in the absence of a host and are the smallest free-living organisms; they have a unit membrane but no cell wall as do bacteria.
Plasma Membrane
A lipid/protein/carbohydrate complex, providing a barrier and containing transport and signaling systems.
plasma membrane
This is a lipid bilayer much like the cytoplasmic (plasma) membrane of other cells.
Plasma is the liquid component of the blood. Mammalian blood consists of a liquid (plasma) and a number of cellular and cell fragment components as shown in Figure 21. Plasma is about 60 % of a volume of blood; cells and fragments are 40%.

plasma cell A mature, differentiated B lymphocyte chiefly occupied with antibody synthesis and secretion; a plasma cell lives for only five to seven days.
The plasma membrane is a lipid bilayer membrane that separates the cell from its environment and regulates the transport of molecules and signals into and out of the cell.
The nuclear envelope is the membrane around the nucleus of the cell.
The plasma membrane is constituted by a phospholipidic bi-layer with proteins incrusted through it from outside to inside.

Plasminogen activator inhibitor-1 (PAI-1) plasma levels have been consistently related to a polymorphism (4G/5G) of the PAI-1 gene. The renin-angiotensin pathway plays a role in the regulation of PAI-1 plasma levels.
Solutions of salt or sugar, denser than the plasma, give them a stellate or crenated appearance (exosmosis) (Fig. 453, d), but the usual shape may be restored by diluting the solution to the same tonicity as the plasma.
Because, as you might imagine, a vesicle swimming up against a plasma membrane, it doesn't just fuse. It's very difficult for that to happen. So it has to assemble a whole bunch of macromolecules at that spot.
The kidney tubule cells have different proteins in the plasma membrane facing the inner side of the tubule from the proteins in the plasma membrane on the outer surface of the cells.
If there is not enough MTHFR activity, plasma homocysteine levels may rise, which in turn increases the risk of cerebrovascular, peripheral vascular, and coronary heart disease, as well as up to a ten-fold increase in the risk for venous thrombosis.

Such a solution is isotonic with most body fluids like plasma, interstitial fluid, and intracellular fluid.) You remember that the appropriate solution should be approximately .15 molar (or 300 mOsm/L).
Their antigen receptors are surface immunoglobulins (antibodies). They recognize peptides directly and secrete antibodies by differentiating into plasma cells. They also exist as long-lived memory cells.
