Synovial Joint Histology (Msq Drill 205)

1. In which zone are the collagen fibers parallel to the surface?

Superificial tangetial zone

Middle transitional zone

Deep zone

Calcified zone

2. Name the articular cartillage layer:

Smooth nearly frictionless surface. Thin collagen fibrils parallel surface, chondrocytes elongated, proteoglycan content lowest and water content highest.

Calcified zone

Superficial tangetial zone

Middle transitional zone

4. Since the articular surface does not have a blood supply, how is material delivered and removed from the articular surface?

Through penetrating canaliculi

Through nereaby harvesian canals

By synovial fluid

5. The calcified zone is located right next to the:

Spongy bone

Periosteum

Subchondral bone

8. Which of the following are the two major types of cells found in the synovial membrane?

Type A - macrophage like - remove debris from joints

Type A - fibroblast like - secrete hyaluronic acid found in synovial fluid

Type B - macrophage like - remove debris from joints

Type B - fibroblast like - secrete hyaluronic acid found in synovial fluid
