Q

Is hypodermic (subcutaneous tissue) a part of skin?

A

No.

It is essentially adipose tissues. 
It does anchor the skin to underlying organs and provide sites for nutrient storage. 
It is also a shock absorber.
It insulates deeper tissues

16
Q

What is the most cells in epidermis?

A

Keratinocytes

Produce keratin, the fibrous protein that makes epidermis a tough and protective layer.

17
Q

—- — — in epidermis, are important in alerting and activating immune system cell to a threat such as bacteria or viral invasion.

A

Epidermal dendritic cells

18
Q

— — are seen at the junction of epidermis and dermis. It is associated with nerve endings and serve as touch receptors.

A

Merkel cells

19
Q

What are included in skin appendages?

A

Cutaneous glands, hair and hair follicles, nails

20
Q

The cutaneous glands are all — — that release their secretions to the skin surface via ducts.

A

Exocrine glands

21
Q

Cutaneous glands are formed by the cells of the — —, they push into deeper skin regions and ultimately reside almost in the dermis.

A

Stratum basale

22
Q

Sebaceous glands’ ducts usually empty into — —, but some open directly onto skin surface.

A

Hair follicle.

23
Q

What is the function of sebum?

A

Keep skin moist and soft
Contain chemicals to kill bacteria
Prevent hair from brittle

24
Q

Hair produced by —.

A

Hair follicles

25
Q

Hair pigment is made by — in the —.

A

melanocytes, hair bulb

26
Q

When the burn is considered critical?

A
  • over 25% of body second degree burn
  • over 10 % of the body third degree burn
  • third degree burn on fave, hands, or feet
27
Q

Which structure of skin produces the patterns for fingerprints?

A

Papillary layer of the dermis

28
Q

How the integumentary system protect body from desiccation?

A

By containing water proofing glycolipid and keratin.
Protective protein prevent water loss from skin in stratum corneum.

Desiccation: drying out

29
Q

How the integumentary system protect body from ultraviolet radiation ?

A

melanin produced by melanocytes offers protection from ultraviolet radiation.

30
Q

How vt.D can be synthesized?

A

Modified cholesterol molecule in skin converted vt.D by sunlight.

31
Q

What are located in reticular layer in dermis?

A

Blood vessels
Sweat and oil glands
Deep pressure receptor

32
Q

What are the two types of fibers composed of dermis?

A

Collagen fiber-toughness

Elastic fiber-elasticity

33
Q

What is associated danger from burn?
