LOCOMOTION IN HUMANSTHE SKELETAL SYSTEM

MADE UP OF TWO COMPONENTSBONE & CARTILAGE


LOCOMOTION IN HUMANSWHAT PURPOSE DOES BONE SERVE?

SITES TO ATTACH MUSCLESTRUCTURE AND SUPPORTPROTECTIONSTORAGE OF MINERALS

(CALCIUM)BLOOD CELL FORMATION


LOCOMOTION IN HUMANSHOW DO BONES FORM?

THEY START OUT AS “REGULAR” CELLS CALLED OSTEOBLASTS

OSTEOBLASTS MIX WITH COLLAGEN, CALCIUM, AND PHOSPHATE TO CREATE A “CEMENT” THAT HARDENS AND FORMS OSTEOCYTES (BONE CELLS)

OSTEOCYTES ARRANGE THEMSELVES IN CONCENTRIC CIRCLES FORMING BONES, BUT STILL ALLOWING CIRCULATION TO OCCUR WITHIN THE BONE

SPACE INSIDE BONE IS ALSO FILLED WITH MARROWMARROW (RED AND YELLOW)

RED MARROW CREATES RBC’S, WBC’S, AND PLATELETS


LOCOMOTION IN HUMANSWHAT IS CARTILAGE?

A FLEXIBLE CONNECTIVE TISSUEALL SKELETALS IN EMBRYOS START OUT AS

CARTILAGE, SLOWLY TURNS INTO BONE AS YOU GET OLDER (OSSIFICATION)

CHILDREN’S BONES HAVE MORE CARTILAGE, SO THEIR BONES ARE MORE FLEXIBLE, WHICH IS WHY THEY DON’T BREAK BONES AS EASILY

LOCOMOTION IN HUMANSTHE MUSCULAR SYSTEM

UNDERSTANDING MUSCLES IS EXTREMELY COMPLEX, BECAUSE IT ISCONTROLLED AT A MOLECULARLEVEL

THE SIMPLE EXPLANATION IS THATTINY FIBERS CALLEDMYOFIBRILS ARE MADE UP OF SPECIAL PROTEINSTHAT INTERACT WITH EACH OTHER AND CAUSEMOVEMENT


LOCOMOTION IN HUMANSMUSCLE

THERE ARE 3 TYPES OF MUSCLESKELETAL (STRIATED) MUSCLE

LOCOMOTION IN HUMANSWHAT IS A TENDON?

CONNECTIVE TISSUEBETWEENMUSCLE AND BONE

WHEN MUSCLECONTRACTS (MOVES)IT PULLS ON THE TENDON WHICHPULLS ON THE BONE,CAUSING MOVEMENT
