A

it has a perichondrium

35
Q

what does type 1 collagen include?

A

tendons, ligaments, skin and bone

36
Q

what is the most abundant collagen type in the body?

A

Type 1

37
Q

What does type 2 collagen include?

A

cartilage

38
Q

what does type 3 collagen include?

A

reticular fibers

39
Q

what is the most abundant adipose tissue in the body?

A

yellow

40
Q

where is brown adipose found?

A

in the axillae (arm pits), the neck and near the kidneys

41
Q

what type of tissue is capable of continous regeneration?

A

epithelial

42
Q

what is the serous membrane layer composed of simple squamous epithelium?

A

mesothelium

43
Q

what is an example of labile cells?

A

adult stem cells

44
Q

what is an example of stable cells?

A

endocrine glands

45
Q

what is an example of permanent cells?

A

neurons

46
Q

what is true of the stratum basale that isn’t of other layers? (3) (BHM)

A

1) bound to the basement membrane by hemidesmesomes
2) highest rate of mitotic division
3) melanin is produced only in this layer

47
Q

which layer of the epidermis is a transparent layer of dead cells only present in thick skin?

A

stratum lucidum

48
Q

order of hair growth (4) MHHH

A

1) matrix cells differentiate, become keratinized and die
2) the hair grows longer as cells are added at the base of the hair root
3) hair growth stops
4) the hair follicle shortens and holds the hair in place

49
Q

where are touch receptors not located?

A

within the hair of the dermis and epidermis

50
Q

if someone has really low vitamin D levels what would you expect to find?

A

1) a lower than normal concentration of calcium and phosphate in the blood
2) a higher than normal concentration of calcium in the urine

51
Q

why does skin appeared flushed after excercising? (2) (AB)

A

1) arterioles of dermis become dilated increasing blood flow to the skin and enhancing the flush
2) blood flow to the dermis increases to remove excess heat from the core

52
Q

if the epidermis is damaged what structure can be a source for a new epithelium?

A

hair follicles

53
Q

what occurs deeper in the hair follice?

A

the number of cells decrease until, at the hair bulb, only the stratum basale is present.

54
Q

what does the decrease in number of cells deep in the hair follicle mean for repair?

A

if the epidermis and superficial part of the dermis are damaged, the keratinocyte stem cells located in the stratum basale of the undamaged part of the hair follice can be a source of a new epithelium

55
Q

name 3 ways to cut an organ

A

1) Longitudinal section (cut through the length of an organ)
2) transverse (cross) section (a cut at a right angle to the length of an organ)
3) oblique section (a cut made at the length of an organ other than a right angle)

56
Q

is vitiligo an effect of UV radiation?

A

no

57
Q

where does nail production occur?

A

in the root

58
Q

in an extensive wound what divides?

A

fibroblasts

59
Q

when fibroblast divide in an extensive wound what occurs?

A

they produce mobile cells that invade the deeper areas of the injury

60
Q

what type of cells do tactile cells include?

A

merkel and cells associated with nervous system function

61
Q

what layer of skin is made into leather products after removal of more superficial and deeper tissues?

A

the dermal layer

62
Q

which layer of the dermis aids in regulation of body temperature?

A

the papillary layer

63
Q

which layer of the dermis forms cleavage lines?

A

reticular layer

64
Q

what are delicate unpigmented hairs that cover the fetus in early development called?

A

lanugo hairs

65
Q

what area does hair growth occur?

A

in the hair bulb

66
Q

are holocrine glands sebaceous or sweat gland?

A

sebaceous

67
Q

which of the layers of the epidermis are new cells formed by mitosis?

A

stratum basale

68
Q

which of the strata have dead cells?

A

stratum corneum and stratum lucidum

69
Q

which strata have live cells?

A

stratum granulosum, stratum spinosum and stratum basale

70
Q

where are the lungs found

A

in the thoracic cavity

71
Q

why is positive feedback helpful in blood clotting but unsuitable for regulation of body temperature?

A

it makes something happen fast, but it does not maintain constant conditions

72
Q

damage to which feedback mechanism will render it unable to maintain homeostasis?

A

damage to any one of the three components will render it unable to maintain homeostasis

73
Q

what is the best description of microvilli?

A

it’s non motile (non moving) containing microfillaments

74
Q

what does brown adipose tissue produce?

A

heat through oxadative metabolism

75

what is the mesothelium?

A

a membrane that lines a body cavity or covers the external surface of the viscera

76
Q

what is an endothelium?

A

the inner lining of the cardiovascular system

77
Q

what is the difference between desmesomes and hemidesmesomes?

A

desmosomes link 2 cells together and hemidesmosomes link 1 cell to the extracellular matrix

78
Q

what do messentaries provide for the organs?

A

a pathway for nerves and blood vessels to reach organs

79
