Anatomy/physiology Skeletol System

Front 1

EPIPHYSIS

Back 1

THIS PART IS AT THE EXTREME ENDS OF THE BONE (EPI=ABOVE)WHERE JOINTS (ARTICULATIONS)FORM

Front 2

ARTICULAR CARTILAGE

Back 2

A LAYER OF HYALINE CARTILAGE CALLED ARTICULAR CARTILAGE, EXISTS TO REDUCE FRICTION AND ABSORB SHOCK AT THE SYNOVIAL JOINTS

Front 3

DIAPHYSIS

Back 3

THE SHAFT OF THE LONG BONE WHICH IS THE DIRECTION AT WHICH THE BONE CAN WITHSTAND THE MOST STRESS

Front 4

METAPHYSIS

Back 4

THE METAPHYSIS IS THE PLACE WHERE THE DIAPHYSIS MEETS THE
EPIPHYSIS.THIS IS WHERE MAJOR BONE GROWTH OCCURS AS WELL AS WHERE BLOOD ENTERS THE BONE

Front 5

PERIOSTEUM

Back 5

A THIN MEMBRANE THAT COVERS THE OUTSIDE OF THE BONE, WHERE TENDONS AND LIGAMENTS ATTACH TO THE BONE. THE OUTER FIBROUS LAYER IS WHERE BLOOD VESSELS, NERVES, AND LYMPHATICS CONNECT TO THE BONE WHILE THE OSTEOGENIC LAYER HAS BONE CELLS NECESSARY FOR THE GROWTH AND REPAIR OF BONE.

Front 6

MEDULLARY (OR MARROW) CAVITY

Back 6

THIS HOLLOW CAVITY, IN THE DIAPHYSIS, IS FOR THE STORAGE OF YELLOW MARROW

Front 7

ENDOSTEUM

Back 7

THIS MEMBRANE LINES THE MEDULLARY CAVITY, AND CONTAINS OSTEOPROGENITOR CELLS
(UNSPECIALIZED BONE CELLS)
