EXAM UNIT 3 (CH. 8-11) Questions And
Answers
Suture: - In between skull bones
- Synarthrotic (immoveable)
Gomphosis: - Joint between teeth and jaw bone (holds teeth together)
- Peridontal ligament links the tooth with jaw bone
- Synarthrotic (immoveable)
Cartilaginous Joints: 2 types:
- Synchondrosis
- Symphysis
Synchondrosis: - Hyaline cartilage that links bones together
2 places:
- between rib and sternum (linking them)
- synarthrotic (immoveable)
- Ex. Epyphyseal line - temporary until bone stops growth

EXAM UNIT 3 (CH. 8-11) Questions And
Answers
Symphysis: - Fibrocartilage joint
- Ex: intervertebral discs & Pubic symphysis (link between 2 pubic bones)
- Amphiarthrotic (slight movement)
Pubic Symphysis: - Joint that does not move except when giving birth (pregnant women
feel pain because this joint usually does not move)
Joints can permit the bones to grow? Yes, because of synchondrosis
Endochondral Ossification: All long bones are hyaline cartilage
Synovial Joints: - Diarthrotic (freely moveable)
6 Types of Synovial Joint Classifications: 1. Ball-and-Socket Joint
