Forearms and thing bones

20

Short bones

Cube like, equal lengths and widths
Wrists and ankles

21

Flat bones

Plate like structures with broad surfaces
Ribs, scapulae, skull bones

22

Irregular bones

Variety of shapes, connected to other bones
Vertebrae, facial bones

23

Sesamoid bones or round bones

Small and nodular
Patella

24

Epiphysis

End of bone expanded portion
Forms a joint with other bone

25

Articular cartilage

Outer surface of epiphysis coated with hyaline cartilage

26

Diaphysis

Shaft of bone between epiphyses

27

Periosteum

Tough vascular converting of fibrous tissue
Firmly attached to bone
Helps firm and repair bone tissue

28

Compact bone

Wall of diaphysis composed of tightly packed tissue
Continuous extracellular matrix with no gaps

29

Spongy bone

Epiphyses made of
Thin layers of compact bone on surfaces

30

Trabeculae

Branching bony plates in spongy bone
Empty spaces reduce weight

31

Medullary cavity

Compact bone in diaphysis of a long home forms semirigid tube with a hollow chamber called

32

Endosteum

Thin members be containing bone forming cells

33

Osteocytes

Bone cells in tiny chambers called lacunae

34

Osteoblasts

Bone forming cells
Deposit bony matrix around themselves

35

Lacunae

Bony chambers that hold bone cells

36

Osteon

Layers of extracellular matrix concentrically cluster around a central canal form a cylinder-shaped unit

37

Haversian canal

Central canals that bone cells form concentric circles around

38

Central canal

Extend longitudinally through bone tissues

39

Perforating canals

Transverse canals that connect central canals

40

Acetabul

41

Intramembranous bone

Broad flat bones of the skull

42

Endochondral bone

Most bones in skeleton
Develop from hyaline cartilage

43

Ossification

Forming an endochondral bond from hyaline cartilage

44

Epiphyseal plate

Band of cartilage
Zone of resting
Proliferating
Hypertrophic
Calcified

45

Osteoclast

Multinucleated cells that break down the calcium matrix
Secrete acid to decompose matrix

46

Bone remodeling

Occurs throughout life as osteoclasts resorb bone tissue and osteoblasts replace the bone

47

Rickets

In children
Absence of vitamin D so calcium is poorly absorbed and deforming bones

48

Hematopoiesis

Process of blood cell formation
Begins in yolk sac outside of embryo

49

Osteomalacia

Same as rickets but in adults

50

Red marrow

Forms red and white blood cells, blood platelets and is red because of hemoglobin

51

Yellow marrow

Stores fat and replaces red as aging in cavities
