Study Notes
Dermis
- The dermis is the thickest layer of skin, located beneath the epidermis.
- It is primarily composed of fibrous, elastic tissue, providing strength and flexibility to the skin.
- The dermis is responsible for nourishing the epidermis through electrolyte and water transfer at the dermoepidermic union.
- Major components include: blood vessels, nerves, hair follicles, and sebaceous glands.
- The dermis has two sublayers:
Papillary Dermis
- The superficial layer of the dermis.
- Responsible for nourishing the epidermis.
Reticular Dermis
- Contains a higher concentration of fibers compared to the papillary dermis.
- Provides structural support to the dermis.
