5. Cartilage Flashcards
What are the characteristics of the fibrous layer of the perichondrium?
Produces Type 1 collagen and elastin
Acts as a transitional zone
What distinguishes one type of cartilage from another?
The Extracellular Matrix differs between types
Where do chondrocytes come from?
Chondroblasts
What are type B Synoviocytes?
What do they produce?
Fibroblast like synovial cells
Produce Hyaluronate and Synovial Fluid
What is the most common form of cartilage throughout the body?
What type of collagen does it use?
Hyaline
Type 2 collagen
What two types of cartilages lack a perichondrium?
Hyaline Articular Cartilage
Fibrocartilage
What kind of collagen do you find in Fibrocartilage?
Type 1 and 2
(predominantly Type 1)
What kind of connective tissue is the perichondrium?
Dense irregular connective tissue
What type of collagen is more common in cartilage?
Type 2
What are the four zones of articular cartilage from superficial to deep?
Superficial -> Intermediate -> Deep -> Calcified
What disease is associated with the reduction of articular cartilage?
Osteoarthritis
What is the layer of connective tissue that holds the cartilage in place, and supports the cartilage from breaking?
Perichondrium
In which zone of articular cartilage do you see round cells and collagen running perpendicular to the articulating surface?
Deep layer
What is the purpose of Fibrocartilage?
Withstands compression and shearing forces
Which zone of the articular cartilage has small, flattened cells?
The superficial layer
Cartilage lacks supply from what three structures?
Nerves
Blood Vessels
Lymphatics
