Skin functions: Protection: bacteria

A

If skin is unbroken, it keeps out our bacteria by secreting anti bacterial agents which keep bacteria out

Skin Functions: Protection: Mechanical

A

Cushions blows, alerts nervous system to pain. If it is unbroken, it inhibits bacteria from penetrating body

Q

Temperature regulation

A

Swearing keeps us cool and capillaries in the skin can allow blood to flush to release heat (blushing) or restrict blood flow to keep us warm
Vaso constriction: keeps heat in
Vaso dilation: keeps us cool
Goosebumps

16
Q

Stratum corneum

A

Outermost layer of epidermis

Shingle like dead cells are filled with keratin (protective protein prevents water loss from skin)

17
Q

Two layers of the dermis

A

Papillary (upper layer)

Reticular (deepest skin layer)

18
Q

Normal skin color determinants ***

A

Melanin: yellow brown or black pigments (darkness)
Carotene: orange/yellow pigment from some vegetables
Hemoglobin: red from blood cells in dermal

19
Q

Skin appendages are found in

A

the dermis

20
Q

Sebaceous glands

A

Most have ducts that empty into hair follicles while others open directly onto skin surface
Glands are activated at puberty
Produce oil

21
Q

Arrector pili muscle

A

Smooth muscle

Pulls hair upright when cold or frightened (goosebumps)

22
Q

First degree burns

A

Only epidermis is damaged

Skin is red and swollen

23
Q

Second degree burns

A

Epidermis and upper dermis are damaged

Skin is red with blisters

24
Q

Third degree

A

Destroys entire skin layer

Burn is gray-white or black

25
Q

Malignant melanoma ***

A

Most deadly skin cancer

Cancer of melanocytes

26
Q

ABCD rule ***

A

A: Asymmetry: two sides of mole do not match
B: Border Irregularity: not smooth edges
C: Color: different colors in pigmented area
D: Diameter: spot is larger than 6 mm in diameter

27
Q

Skin Barriers: Physical ***

A

Hardness (keratin)

Melanin (natural sun block)

28
Q

Skin barriers: chemical ***

A

Secretes oil (sebum controls bacteria)

29
Q

Skin barriers: biological ***

A

Immune system
Blood storage
Vitamin D production

30
Q

What is sebum

A

Mixture of oily substances (oil)

31
Q

What is the sebaceous gland

A

Oil gland found in the dermis

32
Q

What is the sudoriforeous gland (eccrine)

A

Sweat gland found that produces perspiration

33
Q

What is keratin

A

Protective protein that has waterproof properties, hardening protein

34
Q

Melanin

A

Skin color, natural sun block

35
Q

Describe two ways skin controls body temp

A

Sweating; it evaporates and cools air

36
Q

Goosebumps

A

Arrector pili muscle pull on hair follicle-hair stands up hairs trap warm air against the skin

37
Q

1 characteristic of epidermis and dermis

A

Epidermis: superficial and epithelium
Dermis: deep connective

38
Q

Epidermis is

A

Avascular

39
Q

Dermis is

A

Vascular
