WebbIn cardiac muscle, the transverse or (T)-tubules penetrate the muscle cell interior at the level of the Z line, so that cardiac muscle has only one T-tubule per sarcomere. The … WebbPurpose: The purpose of this study was to investigate the regulatory effect of salidroside on the intestinal flora of mice with type 2 diabetes (T2DM) and its protective effect in the body. Patients and Methods: We acclimated 8-week-old mice for 7 days, divided them into 4 groups, and continued dosing for 8 weeks.
T-tubules (transverse tubules) are extensions of the cell membrane that penetrate into the center of skeletal and cardiac muscle cells. With membranes that contain large concentrations of ion channels, transporters, and pumps, T-tubules permit rapid transmission of the action potential into the cell, and also play an … Visa mer T-tubules are tubules formed from the same phospholipid bilayer as the surface membrane or sarcolemma of skeletal or cardiac muscle cells.
