The primary function of the epidermis is to:

• A. Regulate body temperature
• B. Protect underlying tissues
• C. Produce hormones
• D. Supply nutrients to the nail

Answer: (B)

The primary function of the epidermis is to protect underlying tissues. The epidermis serves as the outermost layer of the skin and acts as a barrier, safeguarding the body against environmental factors such as pathogens, chemicals, and physical injuries. It is composed of several layers of cells that continuously renew themselves, maintaining this protective barrier. In addition to its protective role, the epidermis also helps prevent water loss and plays a part in the skin's ability to detect sensations due to nerve endings found in the dermal layer beneath it. While regulating body temperature is an important function of skin overall, it primarily involves the underlying structures rather than the epidermis itself. Hormonal production and nutrient supply to nails are also functions not directly performed by the epidermis. The correct answer highlights the core protective role of the epidermis in maintaining overall skin and body health.
