Functions of skeletal system

Back 1

Support Protection Movement
Storage Hemopoiesis

Front 2

Types of bones

Back 2

short long flat irregular

Front 3

Diaphysis

Back 3

shaft of long bone

Front 4

medullary cavity

Back 4

cavity inside diaphysis houses yellow bone marrow

Back 6

thin layer covering epiphysis acts as cushion

Front 7

periosteum

Back 7

membrane lining outside of diaphysis

Front 8

endosteum

Back 8

membrane lining inside of medullary cavity

Front 9

Compact bone tissue

Back 9

hard, dense outer layer

Front 10

Osteons haversian systems

Back 10

maultiple layers of calcified matrix compact bone is organized into

Front 11

concentric lamella

Back 11

single ring of haversian system, surround central canal contains blood vessel

central canal

Back 12

hole in middle of osteon where blood vessel goes

Front 13

osteocytes

Back 13

bone cells appear as smaller black dots

Front 14

lacunae

Back 14

empty areas where osteocytes lie

Front 15

canaliculi

Back 15

connects lucunae to each other and to central canal

Front 16

Spongy bone tissue

Back 16

porous contains red bone marrow nad trabeculae

Front 17

trabeculae

Back 17

threadlike structures making spongy bone

Front 18

cartilage

contains chondrocytes flexible fibrous gel matrix no blood vessels, difusion to obtain nutrients heals slowly

Front 19

endochondral ossification

Front 22

osteosarcoma

Back 22

tumor forms in bone tissue

Front 23

Chondrosarcoma

Back 23

tumor in cartilage

Front 24
