In the context of skin function, "transcellular" refers specifically to the movement or transport of substances through the cells themselves. This means that a molecule or ion moves not just around the cells, but actually passes through the cell membranes, entering and exiting the cytoplasm of individual cells.

This concept is particularly relevant in understanding how certain substances, such as water, ions, or drugs, can penetrate the skin barrier, which is crucial in fields like dermatology and cosmetology. Transcellular transport plays a vital role in various skin functions, including hydration and the effectiveness of topical treatments, as it allows more direct access to the cellular environment.

The other options, while related to movement through biological systems, do not accurately represent the specific pathway implied by "transcellular." Options referring to movement between cells or across tissues imply different mechanisms that do not involve crossing through individual cell membranes.
