Verified step by step guidance

Understand the role of the integumentary system: The integumentary system includes the skin, hair, nails, and associated glands. Its primary functions are protection, regulation, and sensation.

Identify the cuticle's location and structure: The cuticle is a thin layer of dead skin cells that covers the outer surface of the epidermis, particularly around the nails and hair.

Explore the protective function of the cuticle: The cuticle acts as a barrier, preventing pathogens and harmful substances from penetrating deeper into the skin layers, thus protecting underlying tissues.

Consider the role in preventing dehydration: The cuticle helps to minimize water loss from the body by providing a seal that reduces evaporation from the skin surface.

Conclude the primary function: Based on its protective role against infection and dehydration, the cuticle's main function is to safeguard the underlying tissues, aligning with the correct answer provided.
