Q

What are the four main categories of tissues?

A
  1. Epithelial
  2. Connective

Q

Why does the trachea need to be rigid?

A

So that the airway stays open and we can breathe

Q

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

It only needs to open to pass food. Otherwise, it needs to stay closed so air continues to trachea.

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

60
Q

40x

(4x objective * 10x occular)

61

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.
