1

is an avascular specialized fibrous connective tissue

cartilage

2

what has chondrocytes in its matrix

cartilage

3

what functions primarily to support soft tissues and assist in the devel- opment and growth of long bones.

cartilage

4

is the most abundant cartilage in the body and it also serves as a temporary skeleton in the fetus until it is replaced by bone.

hyaline cartilage

5

Matrix of Hyaline Cartilage has what in it?

- proteoglycans
-chondrocytes
- type 2 collagen

6

matrix that is adjacent to chondrocytes is called

territorial matrix

7

is a layer of dense, irregular connective tissue that surrounds hyaline cartilage except at articular surfaces.

perichondrium

8

what provides the nearest blood supply to the avascular cartilaginous tissue.

perichondrium

9

manufacture the cartilage matrix through which nutrients and waste materials pass to and from the cells, respectively.

chondroblasts

10

are mature cartilage cells that are embedded within lacunae in the matrix.

chondrocytes

11

what has type 2 collagen eslatic fibers and has a present perichondrium?

elastic cartilage

12

location of hyaline cartilage

end of long bones

nose

trachea

larynx

13

location of elastic cartilage

ear
auditary canal
epiglottis

14

location of fibrocartilage

iv disc
poobus symph
tendons
meniscus of knee

15

histogenesis of hyaline cartilage happens how

interstitial growth
appositional growth

16

results from cell division of preexisting chondrocytes. This type of growth occurs only during the early stages of cartilage formation and in articular car- tilage and the epiphyseal plates of long bones.

intersitial growth

17

results from differentiation of chondrogenic cells in the peri- chondrium. This type of growth results in the formation of chondroblasts and/or new chondrocytes, which elaborate a new layer of cartilage matrix at the periphery.

appositional growth

18

degeneration of hyaline cartilage happens how

chondrocytes undergo hypertrophy ad die, also the matrix calcifies

19

arthritis is an example of

degeneration of hyaline cartilage

20

It is a specialized type of connective tissue with a calcified extracellular matrix in which characteristic cells are embedded.

Bone

21

functions to protect vital organs, support fleshy structures, and provide a calcium reserve

Bone

22

bone matrix consists of

inorganic (calcified) portion of bone

organic portion of bone

23

about 65% of dry weight

inorganic portion of bone

24

about 35% of dry weight

organic portion of bone

25

what is a layer of noncalcified connective tissue covering bone on its external
surfaces, except at synovial articulations and muscle attachments.

periosteum

26

what is a thin specialized connective tissue that lines the marrow cavities and supplies osteoprogenitor cells and osteoblasts for bone growth and repair.

endosteum

27

These cells are derived from osteoprogenitor cells under the influence of members of the bone morphogenic protein (BMP) family and also transforming growth factor

osteoblasts

28

These spindle-shaped cells are derived from embryonic mesenchyme and are located
in the periosteum and the endosteum.

osteoprogenitor cells

29

what are capable of differentiating into osteoblasts

osteoprogenitor cells

30

mature bone cell

osteocyte
