Final answer:

The sarcolemma is the cell membrane of a striated muscle fiber cell that consists of a plasma membrane, a lipid bilayer, and a glycocalyx outer coat.


Explanation:

The sarcolemma, also known as the myolemma, is the cell membrane of a striated muscle fiber cell.

It consists of a plasma membrane, which is a lipid bilayer, and an outer coat consisting of a thin layer of polysaccharide material (glycocalyx) that contacts the basement membrane.

Through transmembrane proteins residing in the plasma membrane, the actin skeleton inside the cell is connected to the basement membrane and the cell's exterior.
