A
T Tubule
B
Sarcolemma
C

Detailed explanation-1: -Sarcotubular System. The sarcolemma is the plasma membrane of the muscle cell and is surrounded by basement membrane and endomysial connective tissue.

Detailed explanation-2: -As mentioned earlier, the plasma membrane of a skeletal muscle fiber is called the sarcolemma. The sarcolemma invaginates into the cytoplasm of the muscle cell (sarcoplasm). This forms membranous tubules that pass across the muscle cells. These are called transverse tubules (or ‘T tubules’).

Detailed explanation-3: -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.
