Q

Why doesn’t the espophagus need to be permanently open?

49
Q

ID: 2

A

50
Q

ID: 3

A

Epithelial squamous cells

51
Q

This is a slide of skin.

ID: 1

A

Keratinized stratified squamous tissue

52
Q

This is a slide of skin.

ID: 2

A

Dense irregular connective tissue

53
Q

What does “stratified” mean?

A

There are many layers of cells. Some will touch basement layers, others won’t.

54
Q

Why do we need stratified keratinized squamous cells for the epidermis?

A

Water-proofing and protection from abrasion

55
Q

Why are there no nucleai in the upper layers of skin?

A

Because they are dead.

56
Q

This is a slide of skin.

ID: 1

A

Papillae

57
Q

What organ contains moist stratified squamous epithelium?

A

Tongue

58
Q

True or False

The tongue has keratinized stratisfied squamous epithelium.

A

FALSE

59
Q

This slide shows tissues that are ripped and folded. These irregularities are called…

A

artifacts

60
Q

If you begin focusing on a sliede with the scanning lens (4x), what is your total magnification?

A

40x

(4x objective * 10x occular)

61
Q

What objective lense would you select to have a total of 100x?

A

10x

(10x occular * 10x objective)

62
Q

Tendons and ligaments are made of what type of connective tissue?

A

Dense Regular

63
Q

In puberty, vaginal tissue changes from a simple cuboidal to moist stratified squamous epithelium.

Why?

A
  • To protect from acids of menstruation
  • To protect against damage from the rigors of sex
64
Q

What is the difference between dense regular and irregular tissue?

A

Regular: all tissues are paralel and run in the same direction

Irregular: tissues run in chaotic directions

65
Q

What function do dermal papillae serve?

A

To provide O2 and nutrients to the layers above.

66
Q

Burns to the epidermis are much less serious than burns to the dermis.

Why?

A
  • Epidermis burns are superficial (shallow) and will not result in lasting damage or scarring.
  • Dermal burns are much deeper and contain blood vessels. Burns here will result in lasting damage, scarring and possible infection due to exposure of sensitive tissues.
67
Q

What characteristics are shared by all epithelial tissues?

A
  • Comprised an uninterrupted layer of cells
  • Cover nearly all external and internal body surfaces
68
Q

What are the differences between simple, stratified and pseudostratified epithelia?

A

Simple = one layer of cells where all cells touch basal and apical sides.

Stratified = multiple layers of cells where some will touch basement membrane and others won’t.

Pseudostratified = one layer of cells where all cells touch the basement membrane, but only some reach the apical surface. Looks stratified, but isn’t.

69
Q

Name cells found in adipose tissue

A

Adipocytes, fibroblasts

70
Q

Name cells found in dense regular connective tissue.

A
  • collagen fibers
  • fibroblasts
71
Q

What types of cells are found in cartilage?

A

Chondrocytes

72
Q

What is the epithelial layer made of in this slide?

A

Cuboidal epithelial cells

73
Q

What does this slide show?

A

Cilliated pseudostratified columnar epithelial cells

74
Q

What are the lighter colored oval shaped objects in this slide?

A

Goblet cells

75
Q

What is this tissue?

A

cartilage
