1

What type of tissue has stratified cuboidal or columnar epitthelium?

Conjunctiva

2

What type of tissue has stratified sqaumous keratinized epithelium?

Epidermis

3

What type of tissue has stratified sqaumous non keratinized epithelium?

Corneal epithelium

4

What type of tissue has simple squamous epithelium?

Corneal endothelium

5

What type of tissue has simple cuboidal epithelium? also knowns as what kind of layer?

RPE (dont forget pigmentation, thyroid and kindey also have it)
bilayer epithelium

6

Pseudostratified columnar cells are found in what tissue? key characteristic?

Respiratory (i.e. trachea) signature cilia

7

SImple columnar epithelium found where?

large intestines

8

Transitional epithelium found where? what is so unique about it?

Bladder
sizing of cells, apical has large cells and basal is smaller this is normally the opposite in this tissue.

.71 mm

13

BM is about how thick?

40-60 um

Bowmans is how thick?

12um

15

decemets is how thick? does it remain this thick throughout life? what is unique about decemets?

8-12um
no it gets thicker with age
it has NO hemidesmosomes

16

can the bowmans membrane regenerate if damaged? can decemets?

NO leaves a scar.
YES

17

Can corneal epithelium regenerate? can corneal endothelium?

yes as long as bowmans is not damaged, yes.

18

corneal epithelium is normally how many cell layers thick? what types of cells?

5-7
basal cells (one layer)
Wing cells (2-3 layers)
Superficial cells (2-3 layers)

19

what tissue has dense irregular tissue?

dermis of skin, glands

20

what tissue has dense irregular CT?

corneal stroma and sclera

21
