Functions and Structure of the Skin

Flashcards covering the functions, structure, and color of skin based on the integumentary system.

Integumentary system functions

Protects the body, regulates temperature, provides sensation, stores nutrients, and contributes to immunity.

Epidermis

The outermost layer of skin composed of stratified squamous epithelium.

Stratum basale

Innermost layer of the epidermis where new epidermal cells are formed.

Dermis

Inner layer of skin that contains collagen and elastic fibers, sensory receptors, and adipose tissue.

Hypodermis

Subcutaneous layer that attaches skin to underlying tissues and provides insulation.

Pigments determining skin color

Three pigments are melanin (brown), carotene (yellow), and hemoglobin (red).

Melanocytes

Cells producing melanin that contribute to skin color.

Ultraviolet radiation protection

Melanin protects skin against damage from UV radiation.

Ultimate determiner of skin color

Genetics is the ultimate factor determining skin color.

Stratum corneum

Outermost layer of the epidermis formed of dead keratinized cells.
