1
Q
What are the four main categories of tissues?
A
- Epithelial

2
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.

32
A section a long the length of a specimen is called a
longitudinal section
33
A section across a specimen (perpendicular to its length) is called a...
cross section
34
A section of a specimen that is both along the length and across it is called...

45
This is a slide of Hyaline cartilage.
ID: 2

46
This is a slide of Hyaline cartilage.
ID: 3
Nucleus of chondrocyte
47

Adipose
48
ID: 1
Blood vessel
49
ID: 2
Nucleai of fat cells pushed to the side
50
ID: 3
Epithelial squamous cells
51
This is a slide of skin.
ID: 1
Keratinized stratified squamous tissue
52
This is a slide of skin.
ID: 2
Dense irregular connective tissue
53
What does "stratified" mean?
There are many layers of cells. Some will touch basement layers, others won't.
54
Why do we need stratified keratinized squamous cells for the epidermis?
Water-proofing and protection from abrasion
55
Why are there no nucleai in the upper layers of skin?
Because they are dead.
56
This is a slide of skin.
ID: 1
Papillae
57
What organ contains moist stratified squamous epithelium?
Tongue
58
True or False
The tongue has keratinized stratisfied squamous epithelium.
FALSE
59
This slide shows tissues that are ripped and folded. These irregularities are called...
artifacts
60
If you begin focusing on a sliede with the scanning lens (4x), what is your total magnification?
40x
| (4x objective \* 10x occular)
61
What objective lense would you select to have a total of 100x?
10x
| (10x occular \* 10x objective)
62
Tendons and ligaments are made of what type of connective tissue?
Dense Regular
63
In puberty, vaginal tissue changes from a simple cuboidal to moist stratified squamous epithelium.
Why?
* To protect from acids of menstruation
* To protect against damage from the rigors of sex
64
What is the difference between dense regular and irregular tissue?
Regular: all tissues are paralel and run in the same direction
Irregular: tissues run in chaotic directions
65
What function do dermal papillae serve?
To provide O2 and nutrients to the layers above.
66
Burns to the epidermis are much less serious than burns to the dermis.
Why?
* 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
What characteristics are shared by all epithelial tissues?
* Comprised an uninterrupted layer of cells
* Cover nearly all external and internal body surfaces
68
What are the differences between simple, stratified and pseudostratified epithelia?
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
Name cells found in adipose tissue
Adipocytes, fibroblasts
70
Name cells found in dense regular connective tissue.
* collagen fibers
* fibroblasts
71
What types of cells are found in cartilage?
Chondrocytes
72
What is the epithelial layer made of in this slide?
Cuboidal epithelial cells
73
What does this slide show?
Cilliated pseudostratified columnar epithelial cells
74
What are the lighter colored oval shaped objects in this slide?
Goblet cells
75

cartilage
