1

Epithelial Tissue

all epithelial tissue is avascular; cells too close together for blood vessels to pass
through; diffusion of nutrients and wastes can pass through

cells rest on a basement membrane

classified by number of layers and shape of cells

2

how many layers does a simple epithelial tissue have

1

3

how many layers is pseudo stratified

one layer that looks like multiple layers

4

what do the squamous layers look like

flat layers

5

cuboidal

cube

6

columnar

column

7

what is the structure of simple squamous

one layer of flat cells

8

what is the structure of simple cuboidal

one layer of cube cells

9

what is the structure of simple columnar

one layer of column cells

10

what is the structure of stratified squamous

many layers of flat cells; basal layer touches basement membrane

11

what is the structure of stratified cuboidal

many layers of cube cells; basal layer touches basement membrane;

12

what is the structure of transitional

many layers of cube cells that stretch and recoil; basal layer
touches the basement membrane;

13

what is the structure of stratified columnar

many layers of column cells

14

what is the structure of pseudostratified columnar

one layer of column cells that look like many
layers; all cells touch basement membrane;

15

glandular epithelium

(Exocrine Glands); classified by shape; duct system; type of secretion; and mechanism of secretion

16

tubular

elongated

17

acinar

round/grape like

18

alveolar

round

19

simple duct system

unbranched

20

compound duct system

branched

21

serous secretion

watery

22

mucous secretion

mucous

23

mixed secretion

both serous and mucous

24

holocrine

whole cell destruction; sebaceous/oil gland

25

apocrine

apical/top of cell destruction; goblet cell

26

merocrine

no cell destruction; pancreatic cell

27

simple tubular

sweat gland

28

compound acinar

mammary gland

29

compound tubuloacinar

pancreas

30

what is the structure of desmosome

some extracellular space, with areas of dense fibers
