T-tubules are transverse tubules and are invaginations of the surface membrane of muscle cells. Their function is dependent on the type of muscle but generally speaking many of the proteins involved in cellular Ca2+ cycling seem to be concentrated at the T-tubule. You may want to investigate this further.

Transport tubes. They conduct electricity and cause the sarcoplasmic reticulum to release Ca and then the muscle contracts. T tubules go into the cell and as an electrical current goes across the surface, it also goes into tubules therefore causing muscle contraction.
