Study Notes
Skin Disorders and Structure
- Acne is a skin disorder involving chronic inflammation of sebaceous glands due to retained secretions and bacteria.
- Callus forms from continuous exposure to pressure, causing skin thickening, especially on hands and feet.
Skin Components
- Collagen is a fibrous protein providing strength and form to the skin.
- Elastin is similar to collagen but provides elasticity to tissues.
- Keratin is a fibrous protein that's a principal component of hair and nails.
- Melanin are tiny grains of pigment responsible for skin color; produced by melanocytes.
Hair and Skin Anatomy
- Dermis, or true skin, is the underlying layer composed of two parts: papillary layer (outer) and reticular layer (deeper).
- Dermal papillae are cone-shaped elevations at the base of hair follicles, fitting into the hair bulb.
- Epidermis is the outermost layer, consisting of five layers, including stratum corneum (horny layer) and stratum germinativum (deepest layer for cell production).
Skin Glands and Functions
- Sebaceous (oil) glands are connected to hair follicles and secrete sebum, which lubricates and softens hair and skin.
- Sudoriferous (sweat) glands help detoxify the body by excreting perspiration, excess salt, and unwanted chemicals.
Skin Health and Vitamins
- Vitamin A is crucial for skin health, aiding in the repair and elasticity of skin cells.
- Vitamin C plays a vital role in skin and tissue repair and promotes collagen production.
- Vitamin D is essential for calcium absorption and rapid skin healing.
- Vitamin E offers protection from harmful UV rays.
Sensory and Nervous System Components
- Sensory nerve fibers react to sensations like temperature and pressure.
- Motor nerve fibers are distributed to arrector pili muscles, causing goosebumps.
- Tactile corpuscles are sensitive structures in the epidermis that respond to touch and pressure.
Skin Conditions
- Comedo, often known as a blackhead, occurs when a hair follicle is clogged with keratin and sebum.
- Papules are small elevations on the skin that may develop into pustules containing pus.
- Pustules are inflamed papules with a white or yellow center.
- Propionibacterium acne is the bacteria associated with acne.
Professionals in Skin Care
- Dermatologist specializes in skin, hair, and nails diseases and disorders.
- Esthetician focuses on skin cleansing, beautification, and health preservation.
