- Epidermis: Outermost layer of skin; contains melanin for color and keratin for water repellence.
-
Functions of Epidermis:
- Protects underlying tissues
- Retains bodily fluids
- Regulates body heat
- Dermis: Deeper layer of skin containing essential structures.
-
Components of Dermis:
- Blood vessels for circulation
- Nerve endings that facilitate sensation
- Lymphatic vessels connected to the immune system
- Hair follicles for hair growth
- Sebaceous glands that produce oil
- Sweat glands for temperature regulation
Functions of Glandular Secretions
- Sebaceous Glands: Produce oil that moisturizes and protects hair follicles.
- Ceruminous Glands: Located in the ear, they produce earwax for protection and lubrication.
- Eccrine Glands: Sweat glands that help in cooling the body, protecting the skin, and maintaining moisture.
Skin Changes in Older Adults
