3 What are 3 of the 5 basic functions of the integumentary system?

4 The integumentary system protects against what types of tissue damage? List at least two types of damage.

5 Fill in the following blanks. Heat loss activates the body s and the capillaries.

6 What substances are excreted by the integumentary system? List at least three substances.

7 Vitamin D synthesis requires what two factors?

8 It is recommended that individuals receive minutes of unprotected sun exposure a day to prevent against Vitamin D deficiencies.

9 The skin is an, or 2 or more kinds of tissues that together perform a particular function. Another name that the skin goes by is.

10 List the three different types of tissue found within the skin.

11 The epidermis is composed of what type of epithelial cells?

12 The epidermis is avascular. This means that

13 The is the deepest layer of the epidermis and the only layer that receives nourishment from the dermis.

14 The is the only portion of the epidermis that actively divides.

15 Which layer of the epidermis is only present where skin is hairless and extra thick?

16 Cells within the ascending layers of the epidermis get flatter and more filled with. As cells fill with this, they die.

17 Fill in the following blanks. The stratum corneum is the layer of the epidermis, composed of approximately to layers of cells.

18 Cornified or horny cells are filled with keratin and found within what layer of the epidermis?

19 Within the integumentary system, the main function of keratin is to

20 What particular type of cells is responsible for producing keratin?

21 Melanocytes are

22 When a callus forms the epidermis thickens. This is due to

23 Constant rubbing or irritation of the skin can lead to the formation of blisters. What happens when a blister forms?

24 A wart is an epidermal growth on the skin caused by a

25 Necrotizing fasciitis caused by Streptococcus Group A is better known as a

26 What are hives?

27 The dermis is composed of connective tissue.

28 What two types of fibers are found within the dermis?

29 What causes the sagging and wrinkling of the skin as a person ages?

30 What are the two major regions of the dermis?

31 What portion of the dermis contains the projections that form the ridges for fingerprint and footprint patterns?

32 What portion of the dermis contains blood vessels, sweat and oil glands, and deep pressure receptors?

33 What happens when the body s weight puts pressure on the skin over a bony projection, restricting blood flow? This is a two part question. First, Then

34 What layer of skin lies beneath the dermis?

35 The hypodermis is composed of

36 The subcutaneous layer of the skin performs two main functions. What are they?

37 What do melanocytes secrete? Hint: It is a skindarkening pigment.

38 What is our skin color determined by?

39 True or False: Every person has the same number of melanocytes.

40 stimulates melanin production.

41 Albinism is a condition in which

42 Sam suffers from a condition where there is a loss of melanin across scattered areas of his body, which leaves white patches on his skin. What condition does Sam have?

43 In addition to melanin, skin also contains a yellow pigment called.

44 Cyanosis is a condition where there is a decreased amount of oxygen in the blood. People affected by cyanosis look this color.

45 Jaundice is a liver disorder where excess is deposited in the skin.

46 True or False: Body hair is considered a vestigial organ.

47 Dead keratinized cells are not only found in the outermost layer of our skin, or the, but they also found in our.

48 What causes goose bumps?

49 Sudoriferous glands are more commonly referred to as

50 What is sebum?

51 Acne vulgaris is an active infection of the sebaceous glands, which results in either or.

52 What are the two different types of sweat glands?

53 What type of sudoriferous gland responds to stress and becomes active when a person is frightened, upset, in pain, or sexually aroused.

54 Where are eccrine glands typically found?

55 Unlike apocrine glands, which become active during puberty, the glands function throughout your entire lifetime.

56 What is the main source of heat in our bodies?

57 Impetigo, a condition where water-filled lesions develop a yellow crust, is caused by a

58 What type of burn only damages the epidermis?

59 Second degree burns are associated with damage of the epidermis and upper dermis. Oftentimes people suffering from second degree burns will have.

60 Burns are critical if... % of the body has second degree burns or % of the body has third degree burns.

61 Name two of the three different types of skin cancer.

62 Explain the ABCD rule.
