MUSCLE PHYSIOLOGY

Detailed explanation-1: -The sarcolemma is also called the myolemma and is the cell membrane of a striated muscle fiber cell. The function of the sarcolemma is same as that of the plasma membrane of the eukaryotic cells. Thus, the correct answer is option (B), ‘Muscle fibres’.

Detailed explanation-2: -The sarcolemma (sarco (from sarx) from Greek; flesh, and lemma from Greek; sheath) also called the myolemma, is the cell membrane surrounding a skeletal muscle fiber or a cardiomyocyte. It consists of a lipid bilayer and a thin outer coat of polysaccharide material (glycocalyx) that contacts the basement membrane.

Detailed explanation-3: -The plasma membrane of muscle fibers is called the sarcolemma (from the Greek sarco, which means “flesh”) and the cytoplasm is referred to as sarcoplasm (Figure 10.2.
