| Question | Answer |
|---|---|
| Epidermis | Outer Layer |
| Dermis | Dense connective tissue |
| Subcutaneous Tissue | Deeper than the dermis. Not part of the skin. Anchors skin to underlying organs. |
| Dermis | Papillary Layer (upper dermal region). Reticular Layer (deepest skin layer |
| Normal Skin Color Determinants | Melanin (Yellow, brown, or black pigments) Cartone (Orange-yellow pigments from some vegetables) Hemoglobin (Red coloring from blood cells in dermal capillaries, Oxygen contents determine extent of red coloring) |
| Skin Appendages | Glands (Sweat and Sebaceous), Hair, Nails, Hair follicles |
| Sebaceous Glands | Produce oil (lubricant for skin, prevents brittle hair, kills bacteria)Activated by puberty |
| Sweat Glands | Produce sweat, widely distributed in skin |
| Hair | Produced by hair follicle, Consists of hard keratinized epithelial cells Melanocytes provide pigment for hair color |
| Skin Imbalances | Burns: 1st: epidermis 2nd: into dermis 3rd: through dermis |
| Skin Cancer | Abnormal cell mass, Benign and Malignant |
| Benign Skin Cancer | Does not spread, Epidermis or Dermis |
| Malignant Skin Cancer | Moves to other parts of body, Beneath Dermis |
