What is the main component of the extracellular matrix in the dermis that provides resilience and strength?

Collagen

Explanation

Critical for skin integrity and wound healing.

What protein is responsible for the strength and elasticity of the skin?

Collagen

Explanation

Provides structural support and elasticity to the skin.

Which cells in the dermis are responsible for producing collagen and other extracellular matrix components?

Fibroblasts

Explanation

Produces key components for skin strength and repair.

Which layer of the dermis contains blood capillaries and provides nutrients to the epidermis?
