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.
