Endoskeleton

- bones inside the body

- bones made of calcium and collagen

- all vertebrates have bones

- all vertebrates have the same basic structures

1. skull
2. backbone (vertebrae), 
3. rib-cage, 
4. limbs and 
5. limb-girdles
   

Liquid Skeleton

- no bones but tubes filled with water

- usually water animals

- exception to this rule is worms

Exoskeleton

- a hard outer shell made of chitin

- soft on the inside

- all arthropods (geleedpotigen) have an exoskeleton

- they have joints just like us so they can move

- they grow by moulting

- they undergo metamorphosis

Joints

Types: fixed, gliding, bal and socket, hinge & pivot joint. 

Rembember how they move and examples!

Important parts: cartilage, tendons, ligaments, bones, muscles, liquid

How they work: muscles, antogonists

Examples: hip, skull, elbow, knie, radius & Ulna
