  8. SUPPORT AND LOCOMOTION • LOCOMOTION IN THE GRASSHOPPER • EXOSKELETON MADE OF CHITIN • POSSESS JOINTS (WHICH ALLOW FOR FREE RANGE OF MOVEMENT)

  9. SUPPORT AND LOCOMOTION • LOCOMOTION IN HUMANS • THE HUMAN MUSCULOSKELETAL SYSTEM

  10. SUPPORT AND LOCOMOTION • LOCOMOTION IN HUMANS • THE MUSCULOSKELETAL SYSTEM IS BROKEN INTO TWO PARTS • THE MUSCULAR SYSTEM • EXAMPLES • BICEPS • TRICEPS • HAMSTRINGS • WHAT ELSE?? • THE SKELETAL SYSTEM • EXAMPLES • RIBS • RADIUS • FEMUR • WHAT ELSE??

  11. SUPPORT AND LOCOMOTION • LOCOMOTION IN HUMANS • THE SKELETAL SYSTEM • MADE UP OF TWO COMPONENTS • BONE & CARTILAGE

  12. SUPPORT AND LOCOMOTION • LOCOMOTION IN HUMANS • WHAT PURPOSE DOES BONE SERVE? • SITES TO ATTACH MUSCLE • STRUCTURE AND SUPPORT • PROTECTION • STORAGE OF MINERALS (CALCIUM) • BLOOD CELL FORMATION

  13. SUPPORT AND LOCOMOTION • LOCOMOTION IN HUMANS • HOW 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 MARROW • MARROW (RED AND YELLOW) • RED MARROW CREATES RBC’S, WBC’S, AND PLATELETS

  14. SUPPORT AND LOCOMOTION • LOCOMOTION IN HUMANS • WHAT IS CARTILAGE? • A FLEXIBLE CONNECTIVE TISSUE • ALL 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

  17. SUPPORT AND LOCOMOTION • LOCOMOTION IN HUMANS • THE HUMAN SKELETON • JOINTS • POINT IN THE SKELETON WHERE THE BONES MEET • HELD TOGETHER BY LIGAMENTS

  24. SUPPORT AND LOCOMOTION • LOCOMOTION IN HUMANS • WHAT IS A TENDON? • CONNECTIVE TISSUEBETWEENMUSCLE AND BONE • WHEN MUSCLECONTRACTS (MOVES)IT PULLS ON THE TENDON WHICHPULLS ON THE BONE,CAUSING MOVEMENT

  25. SUPPORT AND LOCOMOTION • LOCOMOTION IN HUMANS • MUSCLE MOVEMENT • CONTRACTING VS RELAXING ANTA PG AO I N R I S S T I C

  26. SUPPORT AND LOCOMOTION • WE JUST TALKED ABOUT VOLUNTARY AND INVOLUNTARY MOVEMENT…BUT WHAT ACTUALLY CONTROLS MOVEMENT? • THE BRAIN!! WHICH IS PART OF THE… • …. • …. • NEXT CHAPTER!!
