Study Notes
Skin Structure and Functions
- The dermis layer is responsible for sensory reception and temperature control.
Collagen Function
- Collagen provides strength, structure, and elasticity to the skin.
Epidermis Layers
- The stratum basale layer of the epidermis is responsible for new-cell production.
Sebaceous Glands
- Sebaceous glands produce sebum, an oily substance that helps to moisturize and protect the skin.
Eccrine Sweat Glands
- Eccrine sweat glands are primarily found in the soles of the feet and palms of the hands.
Melanocytes
- The main function of melanocytes in the skin is to produce melanin, the pigment responsible for skin color.
Apocrine Sweat Glands
- Apocrine sweat glands respond to emotional stress and are primarily found in the axillary and anogenital regions.
Epidermis Layers
- The stratum lucidum layer of the epidermis is absent in thin skin.
Sebum Function
- Sebum helps to moisturize and protect the skin, preventing it from drying out.
Skin Color Variations
