Question

Quizplus · Accepted Answer

T-tubules, or transverse tubules, are inward extensions of the muscle cell membrane (sarcolemma) that penetrate into the center of skeletal and cardiac muscle cells. This structure allows for the rapid transmission of action potentials into the cell, ensuring efficient and coordinated muscle contractions.
