Study Notes
Types of Joints and Their Classification
- Joints can be classified by movement: immovable, slightly movable, and freely movable (diarthrosis).
- Synovial joints possess a synovial cavity that separates the articulating bones, allowing for extensive movement.
Structure and Function of Synovial Joints
- Articular cartilage provides a smooth, lubricated surface for joint movement and absorbs shock.
- The inner layer of the articular capsule, known as the synovial membrane, secretes synovial fluid.
- Synovial fluid functions to lubricate joints, nourish articular cartilage, and reduce friction during movement.
- The fibrous capsule, composed of dense irregular connective tissue, helps to stabilize the joint and protects the underlying structures.
Features of Synovial Joints
- Menisci, structures within some diarthrosis joints, divide the articular cavity into compartments and enhance joint stability.
- Bursae act as cushions between bones and tendons and help reduce friction in areas of high movement.
- Tendon sheaths are specialized structures that wrap around tendons, providing protection and reducing friction during movement.
Joint Innervation and Vascularization
- Joints are innervated by nerves that convey pain, proprioception, and reflexes.
- They also receive a rich blood supply, known as vascularization, which supports their health and function.
Ligaments and Joint Stability
- Ligaments connect bones to one another and provide stability to joints by preventing excessive movement.
- Bursitis is inflammation of a bursa, often causing pain and restricting movement.
Tissue Lining
- The synovial cavity in synovial joints is lined by synovial tissue, facilitating the secretion of synovial fluid.
