5 Questions
What is the stratum corneum?
The stratum corneum is the outermost layer of the skin.
Why is the stratum corneum considered the main barrier to cross?
The stratum corneum is considered the main barrier to cross because of its brick and mortar structure.
What are the two pathways for drug molecules to permeate through the stratum corneum?
The two pathways for drug molecules to permeate through the stratum corneum are transcellular pathway and paracellular pathway.
What type of molecules would prefer the paracellular pathway?
Hydrophobic drug molecules would prefer the paracellular pathway.
What is the most efficient way of transport through the stratum corneum?
The transcellular pathway is the most efficient way of transport through the stratum corneum.
Test your knowledge on the stratum corneum and its role as the main barrier in skin permeation. Explore the brick and mortar structure and learn about the different pathways for drug molecules to cross.
