Articulations

• The site where two or more bones meet.
• Is the weakest aspect of the skeleton, because there are different types of bones.

Gives the skeleton mobility and hold the skeleton together

• Immovable
• Sutures- found in the skull- connects different aspects of bone together (e.g. 4 aspects of cranium). Sutures are zig-zag like to increase surface area and helps them to interlock and eventually fuse together as we get older.
• Syndemoses- Immovable, very fibrous tissue ligament
• Gomphases - tooth socket- tooth will fuse to alveolar bone.

Slightly movable- held together by cartilage and there is no joint capsule (chondroblasts produce cartilage)

• Freely movable joint- ball and socket joints. Bones are separated by fluid filled cavities and are stabilised by ligaments and tendons. 
• The inside lining of the joint capsule is a synovial membrane
