1

What id the function of the Epithelial tissue

cover/line

2

What are the common characteristics of all epithelial tissue

avascular, regeneration, supported by connective tissue, made of mostly cells

3

Name the different types of Epithelial tissue

Simple, Stratified, Glandular

4

What are the subcategories of simple epithelial tissue

simple squamos, cuboidal, columnar, pseudostratified

5

Describe simple squamos

flat cells, diffusion, lungs

6

Describe simple cuboidal

cube-like cells, secrete and absorb, kidney tubules

7

Describe simple columanr

secrete absorb, digestive

8

Describe pseudostratified

secrete(mucus), trachea

9

Startified Squamos

protection, outside of skin, lining of mouth

10

Function of connective tissue

supports, insulates, transports, protects

11

subcatagories of connective tissue

proper (loose, dense) cartilage, bone, blood

12

loose connective tissue

areolar, adipose, reticular

13

areolar

wraps/cushions organs

14

adipose

provides reserve food feul. Under skin

15

reticular

forms soft skeleton. Spleen

16

dense connective tissue

dense reg, dense irreg, elastic

17

dense reg connective tissue

attaches muscle to bone. ligaments and tendons

18

dense irreg connective tissue

withstands tension. Capsule surrounding joint

19

elastic

allows recoil after stretching. Arteries, aorta, heart

20

Kinds of cartilage

hyaline, elastic, fibrocartilage

21

hyaline cartilage

supports/ reinforces. covers end of long bones

22

elastic cartilage

maintains shape and structure. ear

23

fibrocartilage

absorbs shock. intervertebral discs

24

bone

supports/protects

25

blood

transports. blood vessels

26

types of muscle tissue

skeletal, cardiac, smooth

27

skeletal muscle

voluntary

28

cardiac muscle

propels blood. walls of heart

29

smooth muscle

propels objects through passageways. hollow organs

30

nerve tissue

conducts and controls. transmits signals. brain and spinal cord

31

types of tissue repair

regeneration, fibrosis

32

regeneration

same kind of tissue replaces destroyed tissue

33

fibrosis

connective tissue replaces destroyed tisue (scar tissue)

34

steps of tissue repair

1. inflammation
2. building new tissue/ organization restores blood supply
3. regeneration and fibrosis

35

what regenerates well, moderate, and what has no regenerative capacity

well: epithelial tissues, areolar conn tissue, dense irreg conn tissue, blood-forming tissue
Moderate: smooth muscle and dense reg conn tissue
none: cardiac muscle, nervous tissue of brain and spinal cord

36

polarity of epithelial

exhibit apical-basal polarity

37

apical surface

(upper free) exposed to exterior or cavity. May be smooth and slick. Most have microvilli. some have cilia

38

basal surface

(lower, attached) scaffolding for cell migration in wound repair. glycoprotein and collagen fibers lie adjacent

39

GLANDS
