The cell membrane, also known as the plasma membrane, separates the intracellular material from the extracellular material. This selectively permeable barrier controls the passage of substances in and out of the cell, helping to maintain cellular homeostasis.
Cell membranes separate the intracellular and extracellular fluid compartments. The intracellular fluid is contained within the cells, while the extracellular fluid surrounds the cells. Transport proteins in the cell membrane regulate the movement of substances between these compartments.
