Surfaces of epithelial tissue

Lateral surface

Apical (free) surface

Basal surface

2

Apical

Nothing touching it

3

Avascular

No blood supply

4

What is the one cell that goes through mitosis

Basala

Dudes

5

Covering and lining

Arrangement of cells into layers reflects their location & function

6

Layers of epithelium

Simple (unilaminar) epithelium

Pseudostratisfied epithelium

Stratisfied (multilaminar) epithelium

7

Simple epithelium

Unilaminar

Only one layer

8

Psuedostratisfied epithelium

False layer; looks like something it's not

Respiratory

Squamous

flat

12

Cuboidal

Cube

13

Columnar

Taller than wide

14

Transitional

Extra tissue, layers of cuboidal to expand and contract

Bladder, uterus

15

How do you name an epithelium tissue?

Layers, shape, epithelium

16

Characteristics of epithelial tissue

-arranged in continuous sheets
-lacks matrix
-tight junctions
-high capacity for cell division (mitosis)
-covers outside

17

Cilia

Protein

18

Pseudostratified columnar

Nuclei not in straight line

19

Microvilli

Slows down for secretion & absorption

Stratified squamous

Skin

22

Stratified cuboidal

Sweat gland

23

Transitional

Bladder
Stretch to hold fluid

24

Glandular epithelium

Specialized epithelial cells organized to form glands that secrete substances into ducts onto a surface or into the blood

25

endocrine glands

Thyroid gland

Secrete hormones

26

Exocrine glands

Duct glands

Secrete their products into a duct
Sweat, oil, digestive enzymes

27

Lumen

Cavity
Open area
