1. T tubules or the transverse tubules are invaginations of the sarcolemma penetrating into the myocyte interior, forming a highly branched and interconnected network that makes junctions with the sarcoplasmic reticulum.
2. These tubules are selectively enriched with specific ion channels and proteins crucial in the development of calcium transients necessary in excitation contraction coupling, thereby facilitating a fast-synchronous contraction of the entire cell volume.
3. They are unique to straited muscle cells.
