Anatomy Of The Bone

Front 1

Diaphysis

Back 1

A hallow tube/shaft made of hard compact bone .

Rigid and strong structure, light enough enough in weight to permit movement

Front 2

Medullary cavity

Back 2

Hallow area inside the diaphysis of a bone

Contains soft yellow bone marrow ( an inactive fatty form of marrow found in adult skeleton)

Front 3

Epiphysis

Back 3

Ends of the Bone

Red blood marrow fills in small spaces in the spongy bone composing the epiphysis

Front 4

Articular Cartilage

Back 4

A thin layer of cartilage covering wash epiphysis, functions like a small rubber cushion

Front 5

Periosteum

Back 5

A strong fibrous membrane covering a long bone except at the joint surfaces, where it is covered by articular cartilage

Front 6

Endosteum

Back 6

A fibrous membrane that lines the medullary cavity

Front 7

2 main types of connective tissue

Back 7

Bone and cartilage

Front 8

Haversian Systems

Back 8

Osteons

Front 9

Haversian Canals

Back 9

Composed of calcified matrix arranged in multiple layers resembling rings of an onion

Front 10

Trabeculae

Back 10

Needle like threads of spongy compact bone

Front 11

Concentric Lamella

Back 11

Each ring of the osteons

Front 12

Osteocytes

Back 12

Bone cells

Front 13

Central canal

Back 13

Contains blood vessel in bone

Front 14

Lacunae

Back 14

Hard layers of llamelae in little spaces where osteocytes lie

Front 15

Canaliculi

Back 15

Tiny passageways or canals

Front 16

Cartilage

Back 16

A specialized, fibrous connective tissue covering the bone

Front 17

Chondrocytes

Back 17

Cartilage cells
