The layer of dead keratinocytes, also known as the stratum corneum, provides crucial protection to the body.
Protection Provided by the Stratum Corneum
The stratum corneum, the outermost layer of the epidermis, plays a vital role in maintaining overall health. Here's a breakdown of its functions:
- Protection from Infection: It acts as a barrier against bacteria, viruses, and other pathogens, preventing them from entering the body.
- Protection from Injury: It cushions underlying tissues from physical damage, such as abrasions and cuts.
- Prevention of Dehydration: It helps to minimize water loss from the body, preventing dehydration.
- Prevention of Foreign Substance Penetration: It limits the absorption of harmful chemicals and irritants from the environment.
- Temperature and Moisture Regulation: It aids in controlling body temperature and maintaining optimal moisture levels.
In summary, according to information from 08-Apr-2020, the layer of dead keratinocytes protects underlying tissues from infection, injury, and dehydration, prevents penetration of foreign substances, and helps to regulate the body's temperature and moisture balance.
