Sarcolemma, Biology

Sarcolemma

The muscle fibre is surrounded by a cell membrane called sarcolemma. The sarcolemma connects with a complex system of transverse tubules, called T-system that runs across the muscle cells near the Z-lines. The T-tubules appear as invagination of the sarcolemma into the interior of the fibre. The muscle fibre is also surrounded by a sleeve-like structure called sarcoplasmic reticulum, which is involved in the initiation of muscle contraction.
