1. Joints Functions of joints Hold bones together Allow for mobility
Ways joints are classified
Functionally (how much they can move)
Structurally (what separates the two bones that are articulated)

2. FUNCTIONAL Classification of Joints
Synarthrosis
Immovable
Amphiarthrosis
Slightly movable
Diarthrosis
Freely moveable

3. STRUCTURAL Classification of Joints
Fibrous joints
Generally immovable
Cartilaginous joints
Immovable or slightly moveable
Synovial joints
Freely moveable

4. Summary of Joint Classes
[Insert Table 5.3 here]
Table 5.3

5. Fibrous Joints Bones united by fibrous tissue Types: Sutures
Held together by short fibers- no movement
Example:
Coronal Suture
Syndesmoses
Held together by longer fibers- slight movement
Distal end of tibia and fibula p169

6. Cartilaginous Joints Bones connected by cartilage Example:
Pubic symphysis
Intervertebral joints

7. Synovial Joints Articulating bones are separated by a joint cavity
Synovial fluid is found in the joint cavity
Ligaments reinforce the joint

8. Structures Associated with the Synovial Joint
Bursae—flattened fibrous sacs
Lined with synovial membranes
Filled with synovial fluid
Not actually part of the joint
Found where muscles, ligaments and/or tendons may rub on bone
Tendon sheath
Elongated bursa that wraps around a tendon
