Final answer:
The notable quality of the stratum corneum is that it's constantly shedding dead cells to protect underlying tissues.
Step-by-step explanation:
The quality that is notable about the stratum corneum is that it is constantly shedding dead cells. This layer is the most superficial layer of the epidermis, consisting of 15 to 30 layers of dead, keratinized cells. The stratum corneum serves numerous protective functions, including preventing microbial penetration, dehydration, and abrasion of underlying tissues. It is periodically replaced by new cells that originate from the lower layers of the epidermis, and the entire layer is replaced roughly every 4 weeks, demonstrating its dynamic nature.
