A

Connective Tissue

26

A

Connective Tissue

28
Q

What tissues job is to…give an immune response? (WBCs attack foreign invaders)

A

Connective Tissue

29
Q

What are the four broad categories of connective tissue?

A
  1. Fibrous (loose and dense)
  2. Adipose
  3. Supportive (cartilage and bone)
  4. Fluid (blood and lymph)
30
Q

What are the 3 types of matrix fibers in fibrous CT?

A
  1. Collagenous fibers - collagen (most abundant protein)
  2. Elastic fibers - elastin
  3. Reticular fibers - reticular tissue
31
Q

What type of matrix fiber (fibrous CT) has flexibility and strength but not stretch/recoil?

A

Collagen (most abundant protein)

32
Q

What type of matrix fiber (fibrous CT) has flexibility, stretch, and recoil?

A

Elastin

33
Q

What type of matrix fiber (fibrous CT) is thin, branched, not strong, but supports networks for certain organs?

A

Reticular fibers

34
Q

What are the four main types of cells in fibrous CT and their functions?

A
  1. Fibroblasts - produce fibers/ground substance
  2. Macrophages - phagocytic; immune response
  3. Leukocytes - WBCs/immunities
  4. Adipocytes - (not adipose tissue)
35
Q

What is the purpose of ground substance?

A

Protect, lubricate, reduce friction

36
Q

Where is loose connective tissue found? Dense CT?

A

both are found between tissues/organs (binding)

37
Q

Which type of CT has more ground substance: loose or dense?

A

Loose - cells are widely spaced, abundance of ground substance, empty space
(Dense has minimal ground substance, fibers more tightly packed)

38
Q

What type of cells make up adipose tissue?

A

Adipocytes - densely packed/isolated clusters

39
Q

What are the two types of adipose tissue?

A
  1. White adipose - found in adults, used for insulation, anchor, cushion, and body shape
  2. Brown adipose - found in fetuses, infants, and kids, used for heat generating, has an abundance of blood vessels
40
Q

What is the purpose of cartilage (supportive CT)?

A

Gives shape (ex: external ear, tip of nose, larynx)

41
Q

Is cartilage vascular or avascular?

A

Avascular - very slow to heal

42
Q

What type of cells make up cartilage?

A

Chondroblasts –> chondrocytes

43
Q

What are the 3 types of cartilage?

A
  1. hyaline
  2. elastic
  3. fibrocartilage
44
Q

Osseous tissue has what type of matrix?

A

Hard and calcified

45
Q

What cell types make up osseous tissue (bone)?

A

Osteoblasts –> osteocytes

46
Q

What is the function of osseous tissue?

A
  1. physical support
  2. leverage for muscle action
  3. protective enclosure
  4. reservoir for minerals (calcium/phosphorus)
47
Q

What are the two types of osseous tissue?

A
  1. compact (on top)

2. spongey

48
Q

What is blood (supportive CT) made up of?

A

formed elements

49
Q

What is the ground substance in blood called?

A

Plasma

50
Q

What is the function of blood (supportive CT)?

A

transports cells and dissolved materials, clotting fibers

51
Q

What is made up of nervous tissue?

A

Brain, spinal cord, nerves

52
Q

What cell types make up nervous tissue?

A
  1. neurons (specialized)

2. neuroglia (protect/assist neurons)

53
Q

What is the function of the following nervous tissue cell parts:

  1. Dendrites
  2. Axons
A
  1. receive signals

2. conduct nerve impulses

54
