Transverse Tubules

These are extensions of the cell membrane that penetrate into the center of skeletal and cardiac muscle cells, facilitating the uniform contraction of the muscle.

Sarcolemma

The thin, plasma membrane that envelopes a muscle cell (fiber), playing a critical role in muscle contraction.

Z Lines

Positions within muscle fibers that mark the boundaries of sarcomeres, playing a critical role in muscle contraction by anchoring actin filaments.
