Answer:

A skeletal muscle fiber is surrounded by a plasma membrane called the sarcolemma, which contains sarcoplasm, the cytoplasm of muscle cells.

Explanation:

Muscles(muscle fibers) are tissues in the body responsible for the movement and positioning in the human body.

The plasma membrane of a skeletal muscle fiber is called the sarcolemma.

The sarcolemma allows for the easy passage of calcium through the cells of the muscles.

The sarcolemma is made up of the following:

  • A bilayer that is made up of lipids
  • A thin coated polysaccharide called glycocalyx.

Therefore, plasma membrane of a skeletal muscle fiber is called the sarcolemma
