• Yellowish skin coloration which is many times caused by liver disease

• “Bili” lights are used to treat this condition in newborns.

• Jaundice

2

• Bluish skin color due to low oxygenation of the blood.

• Cyanosis

3

• Sweat glands that are active throughout life. Respond to elevated body temperature, release sweat onto the surface of the skin through a pore.

• Eccrine glands

4

• Sweat glands that become active at puberty. Produce moisture when a person is upset, frightened, in pain or sexually aroused. Duct opens into a hair follicle.

• Apocrine gland

5

• Projection of dermal blood vessels at the base of a hair follicle that supplies nourishment.

• Hair papilla

6

• This layer consists of adipose tissue and loose, areolar C.T. Major blood vessels that supply the skin are located here.

• Subcutaneous layer

7

• These are formed by ridges in the dermis. They are determined by genetics, but are also influenced by fetal movement in the womb, so that even identical twins each have a unique set of these.

• Fingerprints

8

• This epidermal layer is only present in the thicker skin on the palms of the hands and soles of the feet.

• Stratum lucidum

9

• This is the deepest layer of the epidermis. Cells in this layer frequently undergo mitosis, producing new cells to compensate for those lost by desquamation, (sloughing).

• Stratum basale

10

• This is the outermost layer of the epidermis. It is composed of 20-30 layers of dead, flattened keratinocytes, and provides a tough, waterproof barrier for the skin.

• Stratum corneum

11

• Smooth muscle attached to the base of each hair follicle. Contracts when the body chills, producing “goose bumps.”

• Arrector pili muscle

12

• This can develop when a person or animal lies in one position for a long period, so that pressure on prominent body parts restricts blood flow to the tissue, causing tissue necrosis (death).

• Methods used to prevent formation of this include: frequently changing body position, massaging the skin, adequate fluid intake and eating foods rich in protein.

• Decubitus ulcer

13

• Acne is caused by a disorder of this gland.• Gland associated with each hair follicle; it

secretes sebum

• Sebaceous gland

14

• The 4 cardinal signs of this are: redness, swelling, heat and pain.

• The body’s normal response to an injury or stress.

• Inflammation

15

• The body’s normal response to this is goose bumps, vasoconstriction of the dermal blood vessels and shivering.

• Hypothermia

16

• The body’s normal response to this is vasodilation of the dermal blood vessels and sweating.

• Hyperthermia

17

When phagocytes eat an infectious agent, they release this chemical which causes the hypothalamus to raise the set point for body temperature, resulting in a fever.

Interleukin 1

18

• Type of burn that only involves the epidermis.

• Superficial, partial-thickness burn. Heals in a few days to 2 weeks, with no scarring.

• First degree burn

19

• Type of burn that involves the epidermis and partial dermis; Blisters form; accessory structures are spared.

• Deep, partial thickness burn. Can heal with no scarring and maintain function of the skin.

• Second degree burn.

20

• Type of burn that involves the epidermis and full dermis. Accessory structures are destroyed. Heals with scarring and loss of functional skin, (can’t sweat, form goose bumps, no hair).

• Deep, full thickness burn. Many times requires a skin graft.

Third degree burn

21

• This consists of the skin, and its accessory structures, which are hair follicles, nails and glands.

• Integumentary system

22

• Production of this chemical is influenced by both genetics and exposure to UV radiation; UV radiation also causes it to darken.

• Melanin

23

• Small, conical projections of dermis that increase surface area contact with the epidermis; helps ensure enough nutrients and oxygen can diffuse to the epidermis from the dermis.

• Dermal papillae

24

The deeper, thicker layer of skin which is composed of dense, irregular connective tissue and contains smooth muscle and nerve cell processes.

Dermis

25

• Thinning hair, thinning epidermis, decreased sensory receptors, decrease in collagen and elastin fibers, decrease gland secretions, decrease in subcutaneous fat – these are the affects of ____

• Aging
