1

epiphysis

- Located at the end of a long bone and articulates with another bone to form a joint

2

articular cartilage

- A layer of hyaline cartilage that coats the articulating portion of the epiphysis.

3

diaphysis

- The shaft of the bone

4

metaphysis

-the widening part of the bone between the diaphysis and epiphysis

5

periosteum

- A tough, vascular covering of dense connective tissue, except for the articular cartilage on its ends.
- Form and repair bone tissue

6

compact bone

-tightly packed tissue

7

spongy bone

-thick layers of compact bone on their surfaces

8

short bone

-Short bones: cube like, with roughly equal lengths and widths. Tarsals and Carpals

9

flat bone

-Flat bones: platelike structures with road surfaces, such as ribs, scapula, and some bones in the skull

10

irregular bone

-Irregular bones: variety of shapes, most are connected to several other bones. Vertebrae that compose the back bone and many facial bones.

11

medullary cavity

- A hollow chamber formed by a tube in the diaphysis of a long bone.

12

endosteum

-a thin membrane containing bone-forming cells
-it lines the medullar cavities

13

marrow

-a specialized type of connective tissue

14

osteocytes

-bone cells

15

osteon(Haversian canal)

-central canal of bone cells

16

lamellae

-layers of extracellular matrix in compact bone

17

lacunae

-bony chambers, which house osteocytes

18

canaliculi

-way for cells to travel throughout the bone

19

perforating canals(Volkmann's canals)

connects the central canals

20

intramembranous bones

-flat bones
-skull, clavicle, sternum, mandible, maxillae, and zygomatic

21

endochondral bones

-develops from hyaline cartilage

22

osteoblasts

-bone forming cells

23

osteoclasts

- Large multinucleate cells that break down the calcified matrix.

24

intramembranous ossification

- The process of replacing embryonic connective tissue to form an intramembranous bone.

25

endochondral ossification

- The process of forming an endochondral bone by replacement of hyaline cartilage.

26

epiphyseal plate

- As spongy bone is deposited in the diaphysis and in the epiphysis, a band of cartilage called epiphyseal plate.
- Allow for growth of bones; growth plates

27

Vitamin D

-necessary for proper absorption of dietary calcium in the small intestine

28

Vitamin A

-necessary for osteoblast and osteoclast activity during normal development

29

Vitamin C

-required for collagen synthesis

30

growth hormone

-stimulates division of cartilage cells int he epiphyseal plates
