1
Q

What are some major structural features of fibrocartilage?

A

chondrocytes, fibrocytes, lots of collagen I, no perichondrium, and it is avascular

2
Q

in fibrocartilage chondrocytes are always what shape?

A

round

3
Q

What are the fiber types within fibrocartilage?

A

dominant type is collagen I and there is some collagen II (some hyaline matrix)

4
Q

Fibrocartilage is avascular because of what?

A

it has no perichondrium

5
Q

What is the function of fibrocartilage?

A
  1. to provide strength; resistant to stretch

2. shock absorber; resistant to compressive forces

6
Q

because fibro cartilage is resistant to stretch it is said to have a high what?

A

a high tensile strength

7
Q

fibrocartilage has a high tensile strength from what?

A

collagen I fibers

8
Q

Fibrocartilage is able to absorb compressive forces due to what?

A

the hyaline cartilage matrix (collagen II)

9
Q

What are some limitations to fibrocartilage?

A

without a perichondrium there is no appositional healing meaning all healing is 100% scare tissue no heal so good

10
Q

initially, fibrocartilage is more like what

A

dense regular ct with fibroblasts and fibrocytes

11
Q

to resist compression and force the fibroblasts produce what?

A

some proteoglycans and some GAG’s

12
Q

fibroblasts will change into what due to the pressure from accumulating molecules?

A

chondrocytes

13
Q

If fibrocartilage undergoes more compressive forces what will you end up with?

A

more hyaline matrix

14
Q

if fibrocartilage undergoes more shearing/pulling forces then you will end up with what?

A

more collagen I by fibroblasts that are there initially

15
Q

In fibrocartilage the fibroblasts will remain and do what?

A

mature into fibrocytes

16
Q

Fibrocartilage is a combination of what?

A

two tissue types (dense regular CT and Hyaline cartilage
