Cartilage collagen fibers are anchored in…
Subchondral bone
Purpose of the cartilage collagen fibers?
They form a meshwork that entraps the larger proteoglycan aggregates
What are cartilage proteoglycan aggregates?
Very large, hydrophilic molecules. They are made of glycosaminoglycans. The pressure of the bound water gives cartilage its elasticity.
Vascularity of Cartilage?
Its avascular.
All components of articular cartilage are produced by…
chondrocytes

Synovial fluid
Where is synovial fluid generated
Synovial membrane
How big is a normal synovial membrane?
1-3 cells thick with an underlying delicate connective tissue network (adipose, capillaries, fibrous parenchyma)
