4 FUNCTIONS OF THE SKELETON:
Shape
Move(ment)
Protection
Standing upright
Slide 4 - Slide
Standing upright + shape
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
STORAGE OF MINERALS AND FATS
The bones stores fats and minerals (calcium).
Slide 8 - Slide
MAKE BLOOD
The bone marrow of larger bones can produce bloodcells.
Platelets, red blood cells and
white blood cells

Slide 20 - Slide
Skeleton
Consist of 3 parts: head, torso, limbs
Has two different types of tissue:
- Bone tissue
(botweefsel)
- Cartilage tissue
(kraakbeenweefsel)
Slide 21 - Slide
Movement
§2 Bones & Cartilage
Slide 22 - Slide
Bones
Give strength, let us move and stand upright
Contain
calcium phosphate
and a bit of
collagen
Slide 23 - Slide
Cartilage
Firm, but very flexible.
Contains a lot of
collagen
Protects bones from damage and makes sure movement is possible.
Slide 24 - Slide
Bone tissue
Cartilage tissue
Slide 25 - Slide
Cartilage tissue (kraakbeenweefsel):
- cellen in groepjes bij elkaar
- elastische tussencelstof
- vooral collageen
Bone tissue (botweefsel):
- cellen in kringen om bloedvaatjes
- harde tussencelstof
- vooral kalkzouten en collageen
Slide 26 - Slide
A change in bone tissue
When younger --> more collagen, less calcium phosphate in bones
When older --> more calcium phosphate, less collagen in bones
Welke grafiek is dan juist?
Slide 27 - Slide
What makes bone flexible?
A
collagen
B
calcium
C
cartilage
Slide 28 - Quiz
What substance makes bone strong?
A
collagen
B
calcium phosphate
C
cartilage
Slide 29 - Quiz
comparing skeletons
The skeleton can tell us something about
-where an animal lives
- what it eats
- what it looked like in the past
Slide 30 - Slide
Protection
Sommige delen van het lichaam bieden bescherming.
Welke delen denk jij?
Schedel: klopt!
De schedel beschermt de hersenen
tegen botsingen, als een helm.
Nekwervels: klopt!
Ze beschermen de
zenuwen
van en naar de hersenen.
Borstkas: klopt!
Dit beschermt de zachte en weke
ingewanden
zoals het hart, de darmen en de longen. Anders zou alles uit je lichaam zakken! Jakkes!
Botten: nee
Dit geeft stevigheid aan het lichaam. de speieren zitten aan de botten vast, en zo kunnen de botten bewegen.
(Hoef)nagels: klopt!
De nagels beschermen de poten tegen beschadiging en verwonding.
Bij sommige dieren zijn de nagels zelfs een wapen!
