JOINTS-SYNOVIAL JOINTS

Anatomy-General

JOINTS-SYNOVIAL JOINTS

1. Characterised by 6 features: articular surfaces covered by hyaline cartilage, the joint enclosed in a capsule, the capsule is reinforced by ligaments and lined by synovial membrane and the joint is capable of degrees of movement.

2. The capsule is itself a ligament.

3. The synovial membrane is attached round the articular margin of each bone. Cells of the membrane secrete hyaluronic acid which is responsible for viscosity of the joint fluid.

4. Fat pads occur in some joints (Harvesian fat pad in the hip, infrapatellar fold, alar fold in the knee).
