1

Axial Skeleton

those one that lie around the body's center of gravity

2

Appendicular Skeleton

bones of the limbs or appendages

3

Articular cartilage

which cover the one ends at movable joints

4

Hyaline Cartilage

Provides sturdy support with some resilience or "give"

5

Elastic cartilage

tolerates repeated bending
ex. external ear and epiglottis

6

Fibrocartilage

great tensile strength and can withstand heavy compression

7

compact bone

smooth and homogenous

8

Spongy bone

composed of small trabeculae of one and lots of open space

9

Long bone

are much longer than they are wide

10

Short bone

typically cube shaped, contain more spongy bone than compact bone

11

Flat bone

generally thin, with two waferlike layers of compact one

12

irregular bone

ones that do not fall into one of the preceding categories

13

sesamoid bones

special types of short bones formed in tendons

14

Diaphysis

shaft

15

periosteum

fibrous membrane covering

16

epiphysis

the end of the long bone

17

epiphyseal plate

a thin area of hyaline cartilage that provides for longitudinal growth of the bone during youth

18

epiphyseal line

thin bone covering the epiphyseal plate after the growth stops

19

yellow marrow

as storage region for adipose

20

red marrow

involved in forming blood cells

21

Endosteum

covers the trabeculae of spongy one

22

Trabeculae

compact bone appears to be dense and homogenous

23

Central(haversian) canal

runs parallel to the long axis of the bone and carries blood vessels, nerves and lymph vessels through the bony matrix

24

Ostteocyte

mature bone cells

25

lacunae

chambers

26

Circumferential lamellae

lacunae arranged in concentric circles around the central canal

27

Osteon(haversian system)

a central canal and all the concentric lamellae surrounding it

28

Canaliculi

tiny canals radiating outward from a central canal to the lacunae of the first lamella and then from lamella to lamella.

29

Perforating(Volkmann's) canal

canal that runs into the compact bone and marrow cavity form the periosteum at right angles of the shaft.

30

Synarthroses

immovable joints

31

amphiarthroses

slightly movable joints

32

diarthroses

freely movable joints

33

Fibrous joint

bones joined by fibrous tissue

34

suture

the irregular edges of the bones interlock and are united by very short connective tissue fibers

35

syndesmoses

the articulating ones are connected by short ligaments of dense fibrous tissue: the bones do not interlock

36

gomphosis

a tooth is secured in a bony socket y the periodontal ligament

37

cartilaginous joints

the articulating bone ends are connected by a plate or pad of cartilage

38

symphyses

the bones are connected by a broad,flat disc of fibrocartilage

39

synchondroses

the bony portions are united by hyaline cartilage

40

synovial joint

those in which the articulating bone ends are separated by a joint cavity containing synovial fluid

41

hinge joint

...

42

saddle joint

...

43

pivot joint

...

44

ball and socket joint

...

45

plane(gliding)joint

...

46

condyloid joint

...
