The dermis is primarily made by fibroblasts, which produce collagen and elastic fibers.
Dermis Composition Breakdown
The dermis, located beneath the basement membrane, is a critical layer of the skin. Here's a detailed look at its composition:
Primary Components:
- Fibroblasts: These are the main cells responsible for creating the structural components of the dermis.
- Collagen Fibers: These fibers provide strength and structure to the dermis.
- Elastic Fibers: These fibers allow the skin to stretch and return to its original shape.
Dermis Layers:
| Layer | Description |
|---|---|
| Papillary Dermis | Upper layer with looser connective tissue, containing blood vessels. |
| Reticular Dermis | Lower, denser layer with tightly packed fibers. |
Fibroblast Function:
- Collagen Production: Fibroblasts continuously manufacture collagen, essential for skin's structure and resilience.
- Response to Injury: They can increase collagen production in response to skin injuries, aiding in healing.
In summary, the dermis is a complex layer of skin, and its main building blocks are the collagen and elastic fibers, which are actively produced by fibroblasts.
