Plasma has been derived from the word that means form or shape so plasma membrane means the membrane that gives shape or form to the cell. This is the reason that cell membrane is also called plasma membrane.
The cell membrane has different lipid and protein compositions in distinct types of cells and may have therefore specific names for certain cell types: 1  Sarcolemma in myocytes. 2  Oolemma in oocytes. 3  Axolemma in neuronal processes - axons. 4  Historically, the plasma membrane was also referred to as the plasmalemma.
