cell touches a gluelike basement _______ that lies under the epithelial tissue

Answer 21

basement membrane

Question 22

why is pseudostratified name is false

Answer 22

because several cell layer appears to be thick but its bot

Question 25

connective tissue proper

Answer 25

fibrous

Question 26

- widely distributed of all connective tissue types - glue embedded in loose matrix that keeps the organs together - consist of fibers that are made of collagen

Answer 26

loose fibrous connective tissue

Question 27

fibrous material that helps the bind the skin muscles, bones and other organs together

Answer 27

fascia

Question 28

- fat - cells contain triglyceride vesicles - white and brown fat - when lipids store tissue - connective tissue

Answer 28

adipose connective tissue

Question 29

clear lipids- storage vesicles that scatter light to give ordinary adipose tissue a whitish appearance - area under skin ; padding at various points - protection, insulation support, nutrient reserve, regulation

Answer 29

white fat - adipose ( connective tissue)(

Question 30

burns its fuel when the body is cold to produce heat. - heat production, regulation - cells contain triglyceride vesicles - fat of neck and tarso

Answer 30

brown fat- adipose ( connective tissue)

Question 31

Answer 32

dense fibrous - regular and irregular (connective)

Question 33

has its collagen fiber bundles arrangedr in a roughly parallel line - doesnt stretch - provide great strength and flexibity - makes up tendons

Answer 33

regular dense fibrous (connective)
