Study Notes
Skin Structure and Function
- The melanocytes in the stratum basale of the epidermis are responsible for producing the pigment melanin.
- Dermal papillae are small, finger-like projections of the dermis that increase the surface area of the dermal-epidermal junction, allowing for more efficient exchange of nutrients and waste.
Burn Classification
- Superficial or first-degree burns involve damage to the epidermis and the upper part of the dermis.
Subcutaneous Layer (Hypodermis)
- The main function of the subcutaneous layer (hypodermis) of the skin is to attach the skin to underlying bone and muscle, and to store energy in the form of fat.
Epidermal Cells
- Keratinocytes are the cells in the epidermis that are responsible for producing keratin, a type of protein that provides strength and elasticity to the skin.
