Earliest sense is for monastic rooms, then prison rooms (1722). Used in Biology 17c., but not in modern sense until 1845.

A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
the cell membrane is as flexible barrier outside of the cell.

the cell membrane
The cell membrane, or plasma membrane, regulates the passage of materials into and out of cells through selective permeability. This means that only certain substances are allowed to pass through the membrane, while others are blocked or actively transported. This selective permeability helps maintain the internal environment of the cell and allows for proper function and communication with the external environment.
