Intracellular transport

Intracellular transport is the movement of vesicles and substances within the cell. Eukaryotic cells transport packets of components (membrane‐bounded vesicles and organelles, protein rafts, mRNA, chromosomes) to particular intracellular locations by attaching them to molecular motors that haul them along microtubules and actin filaments. This method of tranport is often confused with intercellular transport, which deals solely with the movement of cargo between cells not the net movement within a cell. Since intracellular transport heavily relies on microtubules for movement, the components of the cytoskeleton play a vital role in trafficking vesicles between organelles and the plasma membrane.
