-adipocyte (fat cell)
-surrounds and cushions organs
-help store energy

Question 15

examples of adipose CT

Answer 15

subcutaneous fat

Question 16

cartilage

Answer 16

-supporting CT
-has cells called chondrocytes

Question 17

3 types of cartilage

Answer 17

hyaline, elastic, fibrocartilage

Question 18

hyaline cartilage

Answer 18

glassy appearance

elastic cartilage

Answer 19

most flexible

Question 20

fibrocartilage

Answer 20

strongest cartilage

Question 21

bone

Answer 21

-supporting CT
-supports, protects, stores nutrients

Question 22

two types of bone

Answer 22

compact and spongy

Question 23

compact bone

Answer 23

more durable, dense, and strong

Question 24

spongy bone

Answer 24

a lot lighter than compact

Question 25

fluid connective tissue

Answer 25

-fluid CT refers to blood and lymph -blood consists of plasma, erythrocytes, leukocytes, platelets -lymph is derived from plasma

Question 26

muscle tissue

Answer 26

-comprised of cells called muscle fibers -generates tension movement

skeletal, cardiac, and smooth

Question 28

skeletal muscle tissue

Answer 28

striated, voluntary

Question 29

cardiac muscle tissue

Answer 29

striated, involuntary

Question 30

smooth muscle tissue

Answer 30

not striated, involuntary

examples of muscle tissue

Answer 31

movement of bones, blood, food, semen, urine

Question 32

two types of cells in nervous tissue

Answer 32

neurons and glial cells

Question 33

neurons

Answer 33

communicating cells, send impulses

Question 34

glial cells

Answer 34

helper cells, help neurons

Question 35

nervous tissue locations

causes of tissue changes in structure and chemical composition

Answer 36

use, disuse, and age

Question 37

common tissue changes

Answer 37

hypertrophy, hyperplasia, neoplasia, atrophy

Question 38

hypertrophy

Answer 38

increase in tissue size due to increase in cell size

Question 39

hyperplasia

Answer 39

increase in tissue size due to increase in cell number

Question 40

neoplasia

Answer 40

increase in tissue size, uncontrollable

Question 41

atrophy

Answer 41

decrease in tissue size by cell size or number due to lack of use or aging
