1

Consistency of ECM of cartilage

gel-like

2

a type of supportive CT which Bear Mechanical Stress without permanent distortion

cartilage

3

components of cartilage

chondrocytes and ECM

4

the chondrocytes of cartilage are located in a

lacuna

5

a component of cartilage responsible for the synthesis and excretion of ECM materials

chondrocytes

6

nourishment of cartilage is through

diffusion

7

cartilage is vascular or avascular

avascular

8

a dense irregular CT w/c surrounds the cartilage
vascular; has nerves and lymphatic vessels

perichondrium

9

perichondrium is only present in

hyaline and elastic cartilage

10

most common and most studied cartilage

hyaline

11

glassy and transparent/translucent cartilage

hyaline

12

bluish white and transluscent cartilage

hyaline

13

type of cartilage that serves as a temporary skeleton of the bone

hyaline

14

location of hyaline cartilage

Location: trachea, larynx, bronchi, anterior ends of ribs,

15

Function of hyaline

provides smooth surface for movement of joints,
flexibility and support

16

cartilage which Contains elastic fibers


Function = gives support, maintains shape, allows flexibility

elastic cartilage

17

cartilage Yellowish color when unstained

elastic cartilage

18

location of elastic cartilage

Found in external ear, auditory tubes, epiglottis.

19

Function of elastic cartilage

gives support, maintains shape, allows flexibility

20

type of cartilage Intermediate between Dense CT and Hyaline CT

fibrocartilage

21

type of cartilage
contains bundles of collagen in the matrix that are usually more visible under microscopy


fibrocartilage

22

location of fibrocartilage

Found in the pubic symphysis, intervertebral discs, and attachments of certain ligaments.

23

Function of fibrocartilage

support and fusion, and absorbs shocks.

24

cartilage that Do not possess distinct perichondrium

fibrocartilage

25

major component of intervertebral disks

Annulus fibrosus (Type I collagen)
Nucleus Pulposus (Hyaluronic acid)

26

type of supportive CT
Main constituent of the adult skeleton (206)
Mineralized Tissue

OSSEOUS TISSUE

27

Functions of osseous tissue:

>Support soft tissues and provides attachment
>Protects internal organs
>Stores minerals
>Hematopoiesis

28

component of osseous tissue responsible for tenacity,
elasticity, resilience

organic or living components

29

component of osseous tissue responsible for hardness and rigidity

Inorganic (non- living) components

30

found in lacuna(cavities), between layers (lamellae) of the bone matrix; located exclusively at the the surface of the bone matrix

Osteocytes:
