The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a semipermeable biological membrane that …

Membrane, in biology, the thin layer that forms the outer boundary of a living cell or of an internal cell compartment.

1 day ago · 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. In bacterial and plant …

Structure and Composition of the Cell Membrane The cell membrane is an extremely pliable structure composed primarily of two layers of phospholipids (a “bilayer”). Cholesterol and …

Jul 22, 2025 · Explore the cell membrane’s design, a dynamic structure that controls molecular passage, facilitates communication, and provides essential cellular support.

Aug 3, 2025 · Though often overshadowed by more glamorous components like the nucleus or mitochondria, the cell membrane—also known as the plasma membrane—is nothing short of …

Scientists who model membrane structure and dynamics describe the membrane as a fluid mosaic in which transmembrane proteins can move laterally in the lipid bilayer.

We will first investigate the anatomy of the cell membrane and then continue on to study the physiology of membrane transport. The phospholipid bilayer is the main fabric of the membrane.

Although we focus mainly on the plasma membrane, most of the concepts discussed are applicable to the various internal membranes in cells as well. The functions of cell membranes …
