Study Notes
Types of Joints based on Material
- Fibrous Joints: Bones are connected by dense connective tissue.
- Cartilaginous Joints: Bones are connected by cartilage.
- Synovial Joints: Bones are connected by a joint cavity filled with synovial fluid.
Sutures
- Function: Immovable joints that connect bones in the skull.
Synovial Joints
- Defining Characteristic: Presence of a joint cavity filled with synovial fluid.
Symphysis
- Function: Slightly movable joints that provide cushioning and flexibility, typically found in the vertebral column and pelvis.
Tibiofibular Joint
- Type: Syndesmosis (a type of fibrous joint).
- Function: Allows for limited movement between the tibia and fibula.
Types of Fibrous Joints
- Sutures: Immovable joints found in the skull.
- Syndesmoses: Slightly movable joints that connect bones with ligaments.
- Gomphoses: Immovable joints that hold teeth in the sockets of the jaw.
Types of Cartilaginous Joints
- Synchondroses: Immovable joints where hyaline cartilage connects bones.
- Symphyses: Slightly movable joints where fibrocartilage connects bones.
Defining Characteristic of Synovial Joints
- Presence of a joint cavity filled with synovial fluid.
Structures of a Synovial Joint
- Articular Cartilage: Covers the ends of bones, providing a smooth surface for movement.
- Joint Cavity: Space between bones filled with synovial fluid.
- Synovial Fluid: Lubricates and nourishes the joint.
- Articular Capsule: Encloses the joint cavity.
- Ligaments: Connect bones and provide stability.
Defining Characteristic of Cartilaginous Joints
- Bones are connected by cartilage.
