Chapter 6 Flash Cards

Front 1

Dermis

Back 1

Has 2 zones (papillary and reticular) that hold the fingerprints, blood vessels, sweat and oil glands, hair follicles, pressure receptors and phagocytes

Front 2

Hypodermis

Back 2

Holds adipose tissue, anchors skin to the muscle, shock absorber and insulator

Front 3

Hair

Back 3

Dead cells keratinized, grows from hair follicle, three layers of hair that determine texture, color due to melanocytes

Front 4

Nails

Back 4

Keratinized dead cells, growth occurs from the white "half moon" shape, protects ends of fingers, defense, scratching

Front 5

Sweat gland

Back 5

2 types- apocrine and eccrine

Front 6

Sebaceous gland

Back 6

Open into hair follicles, secrete oily mix of fat and dead cells called sebum

Front 7

Functions of skin

Back 7

1.protects against mechanical damage (bumps)

2. Protects against chemical damage

3. Protects against bacterial damage

4. Protects against UV radiation

5. Protects against thermal damage (heats or cold)

6. Protects against desiccation (drying out)

7. AIDS in heat loss/ retention

8.excretes urea/Utica acid (waste)

9.synthesizes vitamin D

Front 8

Keratin

Back 8

Tough, waterproof protein that fills in the dying epidermis cells

Front 9

Melanocytes

Back 9

Makes melanin which is a dark pigment that gives your skin its color
