The skeleton
The skeleton includes bones and cartilage:Bones are harder and cartilage are more flexible. Can you think in any cartilage in your body? HOMEWORK
- Our skeleton supports and gives shape to our body.
- It protects our internal organs.
- We have 300 bones at birth, these grow together to form the 206 when we are adult.
Dislocation:
Types of bones:
Short: vertebraes- body support and stability. Flat: ribs- protect the internal organs Long: femur- help us to move
Fracture:
"a place where two things are joined together"
FIXED: JOINTS DO NOT MOVE: Joints in the skull
JOINTS
SEMI-FLEXIBLE: CAN MOVE A LITTLE: Vertebrae
FLEXIBLE: THEY CAN MOVE A LOT: Elbow, wrists, lnees and ankles.
