Verified step by step guidance

Understand the structure of the skin: The skin is composed of three main layers—epidermis, dermis, and hypodermis. Each layer has distinct functions and tissue types.

Focus on the dermis: The dermis is the middle layer of the skin, located beneath the epidermis. It is primarily responsible for providing strength and elasticity to the skin.

Identify the tissue type in the dermis: The dermis contains dense irregular connective tissue, which is rich in collagen and elastin fibers. These fibers are responsible for the skin's strength and ability to stretch and return to its original shape.

Differentiate the dermis from other layers: The epidermis is the outermost layer and primarily serves as a protective barrier. The hypodermis, also known as the subcutaneous layer, is composed of adipose tissue and provides insulation and cushioning. The stratum corneum is part of the epidermis and consists of dead keratinized cells, offering protection but not elasticity or strength.

Conclude that the dermis is the correct answer: Based on its composition and function, the dermis is the layer responsible for providing strength and elasticity to the skin due to its dense irregular connective tissue.
