1. Types of Joints Definition: The site where two or more bones meet.
Immovable - Fibrous joints
skull
tibia/fibula

2. Types of Joints Immovable - Cartilaginous joints Rib cage
Intervertebral discs

3. Types of Joints Movable - Synovial Joints
Most joints in the body, including all joints of the limbs
Characteristics:
Articular cartilage
Joint cavity/capsule
Synovial fluid
Ligaments
Tendons

4. Joint Tissues Cartilage Three Types Hyaline Elastic Fibrocartilage
2. Functions
Provides support
Shock absorbance
Provides flexibility
Smooth movement

5. Joint Tissues
Cartilage

6. Tissue Types – Hyaline Cartilage
Functions
Provides soft and smooth covering to end of bone (articular surface)
Helps provide smooth and easy movement between bones (at joints)
Provides the starting material for new bone growth
Structure
Matrix is spongy (like jello) and evenly distributed between the cells
Cells (chrondocytes) are found in pairs within capsules called lacunae
Hyaline Cartilage

7. Tissue Types - Fibrocartilage
Functions
Shock absorber for structures subjected to pressure (meniscus, intervertebral discs)
Structure
Tough tissue with matrix of many collagenous fibers
Fibrocartilage

8. Joint Tissues
Ligaments and Tendons – Dense Connective Tissue

9. Tissue Types Dense Connective Tissue
Functions
Ligament- bone to bone connection, stops abnormal movement
Tendon – bone to muscle connection, creates normal movement
Structure
Tough tissue with matrix of many collagenous fibers and a fine network of elastic fibers
Dense Connective Tissue
