Study Notes
Joint Structure and Function
- Every bone in the body is connected to form a joint.
- Joints are lubricated by fluid, enabling smooth movement of parts against each other.
- Synovial fluid is contained within the synovial capsule which holds the fluid in place.
- The synovial membrane, located inside the capsule, is responsible for producing synovial fluid.
Components of Synovial Joints
- Articular cartilage is present in synovial joints and provides a smooth surface for interaction.
- Synovial joints allow for greater flexibility and movement due to their design.
Classification of Synovial Joints
- Synovial joints can be classified according to the shape of their articular surfaces:
- Plane joints
- Hinge joints
- Pivot joints
- Condylar joints
- These joints facilitate gross movement and enable bone growth.
Functions of Joints
- Joints connect and support the bones in the body.
- They provide flexibility, allowing for movement.
- Joints allow for bone growth during development.
Classification of Joints
- Joints can be structurally classified based on the tissue connecting the bones:
- Fibrous joints: Immobile, without a synovial cavity.
- Cartilaginous joints: Also without a synovial cavity but allow limited movement.
- Synovial joints: Highly mobile, characterized by the presence of a synovial cavity.
Fibrous Joints
- Connected by dense connective tissue primarily made of collagen.
- They are further categorized into three types, with each type having its specific characteristics related to movement and structure.
