The skeletal system : The framework of bones and tissues that support the body

The muscular system -Tissues that move parts of the body and operate internal organs

Contract - squeeze or pull together

Cartilage -  Allows joints to move easily, cushions bones and supports soft tissues such as those in the nose and ear

Tendons - join muscle to muscle or muscle to bone

Joints - The places where two or more bones meet

Pivot joint- The end of one bone rotates inside a ring formed by another bone

Gliding Joint - One part of the bone glides over another

Ball and socket joint - The ball shaped head of one bone moves inside a cup shaped pocket

Hinge - The joint moves in only one direction like a door

Ligaments - Holds bones in place at joints

Jobs of the skeletal system

1. Support

2. Movement

3. Protection of organ

4. Produces red blood cells

5. Storage of fat and calcium

Skeletal system

• Cartilage: Tissue that covers the end of the bones

• Purpose : stops bones from rubbing against each other

• Elastic cartilage -stretchy moves east

• Hyaline cartilage - harder to mover - protection -

• 
  

• Growth plates : Make new bone cells - (helps you break)

• Joint- where two bones meet

• Ligament: connects 2 bones

Injuries  -break- sprain
