Q

What is connective tissue composed of?

A

cells and extracellular matrix

33
Q

Are connective tissues highly vascularized?

A

Yes, except cartilage and tendons

34
Q

What type of connective tissue is NOT supplied with nerves?

A

Cartilage

35
Q

A medium that helps binds cell together and allows cells to exchange material between each other

A

Ground substance. Contains water and an array of organic molecules such as hyaluronic acid (provides lubrication) and chondroitin sulfate (provides support and stickiness)

36
Q

Which fiber has larger strong flexible fibers found in bone, tendons, cartilage and ligaments?

A

Collagen fibers

37
Q

Which fiber has smaller strong stretchy fibers that exhibit elasticity?

A

Elastic fibers

38
Q

Where are elastic fibers found?

A

Found in skin, blood vessel walls and lung tissue.

39
Q

Which fiber is made of thin fibers that contain collagen and a glycoprotein coating to provide support and strength around soft organs and the basement membrane in between epithelial and connective tissue?

A

Reticular fibers

40
Q

What are the 3 categories of connective tissue?

A
  • Loose connective tissue
  • Dense connective tissue
  • Supporting connective tissue
41
Q

What type of tissue makes up cartilage, bone tissue, blood and lymph?

A

Supporting connective tissue

42
Q

What fiber type has fibers are loosely arranged around the cells?

A

Loose connective tissues. Types include:
Areolar connective tissue
Adipose tissue
Reticular connective tissue

43
Q

What fiber type has fibers that are packed with fewer cells than loose connective tissue?

A

Dense regular connective tissue
Irregular connective tissue
Elastic connective tissue

44
Q

Does cartilage heal quickly?

A

No. Cartilage heals slowly because nutrients must diffuse through the matrix to the chondrocytes

45
Q

What makes cartilage a unique connective tissue?

A

Avascular. Other types of connective tissue all have rich blood supplies. Because cartilage is avascular, nutrients cannot reach the cells directly via the bloodstream.

46
Q

What type of connective tissue is made by Chondrocytes?

A

cartilage

47
Q

3 types of cartilage

A

Hyaline Cartilage
Elastic Cartilage
Fibrocartilage

48
Q

What is the most common type of cartilage?

A

Hyaline Cartilage

49
Q

Which cartilage overs the ends of bones, allowing them to slide against one another without damage?

A

Hyaline Cartilage

50
Q

Which cartilage forms the outer ear and the epiglottis?

A

elastic cartilage

51
Q

Which cartilage cushions knee joints and the discs between the vertebrae with its collagen packed matrix?

A

fibrocartilage

52
Q

What is osteoid substance?

A

A secretion from osteocytes that eventually hardens and surrounds the cells in an ossified matrix (solid bone)

53
Q

What is osteoid substance composed of?

A

proteins, water, calcium, phosphorous salts

54
Q

What is the name of the small connection channels between osteocytes?

A

canaliculi

55
Q

Why are blood and lymph considered to be fluid connective tissues?

A

Q

What is the main function of blood?

A

transport nutrients, gases, hormones, and wastes
