2. Periosteum
3. Endosteum
4. Epiosteum
5. Exofibrium

Q2 True or false

1. the smallest contractile unit of a myofibril is sarcomere

2- The moveable attachement of a muscle is the origin

3. The direction term that means the opposite of distal is superior

4- Cranial bones joined by suture

5- The bones forming an immovable joint are the parietal and temporal bones

6- In rheumatoid arthritis, the immune system is believed to symmetrically attack the synovial membranes, causing a thickening and inflammation. The joint is invaded by fibrous connective tissue that ultimately makes the joint immovable.
