Was ist ein cytoplasmatischer Schlauch?

The cytoplasmic sleeve refers to a structure found in certain types of cells, particularly in the context of cell communication and transport. It is a narrow channel of cytoplasm that connects adjacent cells, allowing for the direct transfer of ions, small molecules, and other substances. This structure is often associated with cells that are electrically coupled, such as cardiac muscle cells, where it facilitates rapid communication and coordination of contractions. The cytoplasmic sleeve plays a crucial role in maintaining cellular homeostasis and enabling efficient intercellular signaling.
