Proteoglycans

A

Thick gel that shows down pathogenic organisms
Holds tissues together

22
Q

Adhesive protein

A

Bind plasma membrane proteins to collagen and proteoglycans on the outside of the cell

23
Q

Embryonic connective tissue types

A

Mesanchyme- found all throughout embryo
Mucous connective tissue - only in umbilical cord

24
Q

Connective tissue proper types

A

Loose connective tissue , adipose , reticular

25
Q

Aereolar

A

Most abundant tissue type / has all three fibers, six cells , found under skin all over body

26
Q

Adipose tissue

A

Fat tissue

27
Q

Does brown or white adipose tissue have more mitochondria?

A

Brown, making heat, needs to be more active

28
Q

Reticular tissue is made of what tissue type

A

Dense irregular

29
Q

Where is reticular connective tissue found

A

Spleen, thymus, lymph nodes, and bone marrow

30
Q

What two types of dense connective tissue is there?

A

Sense regular and dense irregular

31
Q

Where is dense regular connective tissue found

A

Tendons, ligaments, and aponeuroses

32
Q

Where is dense irregular connective tissue found

A

Skin

33
Q

Where is dense elastic connective tissue found?

A

Ligaments, lung tissue, vocal chords

34
Q

What are 3 types of supporting connective tissue?

A

Cartilage, hyaline, and elastic

35
Q

Does spongy bone have osteons?

A

No

36
Q

Does compact bone have osteons?

A

Yes

37
Q

Fluid connective tissue - two types

A

Blood, and lymph

38
Q

What is liquid matrix in blood called?

A

Plasma

39
Q

What do erythrocytes, leukocytes, and platelets do in blood liquid connective tissue?

A

Clotting, immune functions, transport of O2 and CO2

40
Q

Does lymph liquid connective contain more or less protein than plasma?

A

Less

41
Q

What does lymph connective fluid do?

A

Move cells and substances (lipids) from one part of the body to another

42
Q

Do red blood cells have a nucleus?

A

No

43
Q

Where is hyaline cartilage found?

A

Found at the joints- reduces friction no blood vessels or nerves so repair is very slow

44
Q

Where is elastic cartilage found?

A

Ear, nose, throat canal

45
Q

What does fibrocartilage lack?

A

Lacks perichondrium-

46
Q

What is the function of bone (osseous) tissue?

A

Protects, provides for movement, stores minerals, site of blood cell formation

47
Q

What does bone (osseous) tissue consist of?

A

Matrix containing mineral salts and collagenous fibers and cells called osteocytes

48
Q

What are lamellae in compact bone tissue?

A

Rings of mineralized matrix, made of calcium and phosphate which gives it its hardness

49
Q

What are lacunae?

A

Small spaces between lamellae that contain mature bone cells called osteocytes

50
Q

What are canaliculi?

A

Minute canals containing processes of osteocytes that provides routes for nutrient and waste transport

51
Q

What is a Haversian canal?

A

Contains blood vessels and nerves , allows bone to get oxygen and nutrition without being highly vascular

52
Q

Chondrocytes are located inside of what structure?

A

Lacunae, bone and cartilage
