FUNCTIONS OF THE SKELETON:
  • SUPPORT
  • MOVEMENT
  • PROTECTION
  • PROVIDE SHAPE
  • (BLOOD CELL PRODUCTION)

Slide 4 - Slide

SUPPORT
  • WE CAN'T STAND UP STRAIGHT OR EVEN LIFT OUR HEAD WITHOUT OUR BONES.
  • WITHOUT THEM WE WOULD BE A PUDDING. 

Slide 5 - Slide

MOVEMENT
  • BECAUSE OUR MUSCLES PULL ON BONES AND THE BONES THEN MOVE.
  • OUR MUSCLES ARE ATTACHED TO THE BONES WITH TENDONS.

Slide 6 - Slide

PROTECTION
  • IMPORTANT ORGANS ARE PROTECTED BY BONES.
  • LIKE YOUR LUNGS, HEART AND BRAIN 

Slide 7 - Slide

MAKE BLOOD
  • THE BONE MARROW OF LARGER BONES CAN PRODUCE BLOOD CELLS.
  • PLATELETS, RED AND WHITE BLOOD CELLS

Slide 9 - Video

TYPES OF SKELETONS:
  • EXOSKELETON / EXTERNAL
  • ENDOSKELETON/ INTERNAL
  • LIQUID SKELETON  (NOT A HARD PART OF BODY)


Slide 10 - Slide

ENDOSKELETON
  • THE BONES ARE INSIDE THE BODY.
  • OFTEN MADE OF CALCIUM AND COLLAGEN.

FISH: 2
REPTILES: 1, 12 & TURTLE
AMPHIBIANS: 8 & 10
BIRDS: 6 & 9

Slide 14 - Slide

EXOSKELETON
  • THE BONES ARE OUTSIDE THE BODY.
  • THESE ANIMALS OFTEN NEED TO MOULT TO GROW.
  • THEY OFTEN ALSO DO METAMORPHOSIS.

Slide 15 - Slide

Slide 16 - Video

LIQUID SKELETON
  • THERE ARE NO BONES.
  • THERE ARE TUBES FULL OF LIQUID.
  • THESE ARE USUALLY WATER ANIMALS.
  • WORMS HAVE THIS TYPE OF SKELETON.
