Study Notes
Hypodermis
- Definition: Contains subdermal, sudoriferous, sebaceous glands, blood vessels, and nerves
- Function: Protects from trauma, excretory
- Two zones: Papillary, Reticular
Papillary Layer
- Superficial layer
- Contacts epidermis
- Contains abundant capillaries for epidermis nutrition
Reticular Layer
- Deepest layer
- Contacts hypodermis
- Contains abundant collagen & elastin fibers
Fibers
- Collagen: Strong, flexible, abundant (70%)
- Elastin: Enables skin elasticity, returns to original shape
- Reticular: Forms supportive network
Cells
- Fibroblasts: Stationary cells, produce fibers
- Histiocytes: Motile, phagocytic cells
- Mastocytes: Motile, large cells, defensive actions
