Study Notes
Skeletal Joints
- Joints are the areas where two or more bones come together
- Joints are classified by the type of connective tissue connecting them and the amount of movement permitted
- There are three main types of joints: fibrous, cartilaginous, and synovial
Fibrous Joints
- Composed of fibrous connective tissue
- Little to no movement
- Examples include sutures in the skull, and syndesmoses (between tibia and fibula)
- Gomphoses hold teeth in their sockets
Cartilaginous Joints
- Connected by cartilage
- Limited movement
- Types include synchondroses (connected by hyaline cartilage, example epiphyseal plates) and symphyses (connected by fibrocartilage, example pubic symphysis)
Synovial Joints
- Characterized by a joint cavity filled with synovial fluid and lined by a synovial membrane
- Freely movable
- Examples include hinge, pivot, condyloid, saddle, ball and socket
- Synovial joints are further categorized into the type of movement they permit (uniaxial, biaxial, or multiaxial)
- The joint capsule is enclosed by a fibrous outer layer and an inner synovial membrane
- The synovial membrane secretes synovial fluid, lubricating the joint
- Articular cartilage covers the bones within the joint, cushioning and reducing friction
