3 Questions
What is the composition of cartilage?
Water, inorganic salts, collagens, PGs, and non-collagenous proteins
What is the function of type II collagen in hyaline cartilage?
Provides tensile strength and shape
What are isogenous groups in chondrocytes?
Clusters of recently divided chondrocytes
Study Notes
- Chondrocytes synthesize and maintain the extracellular matrix of hyaline cartilage.
- Chondrocytes can be singular or in clusters called isogenous groups.
- Isogenous groups represent recently divided chondrocytes.
- Chondrocytes produce matrix material and secrete enzymes that degrade cartilage matrix.
- Cartilage is composed of water, inorganic salts, collagens, PGs, and non-collagenous proteins.
- Water and inorganic salts give cartilage resilience and lubricating capabilities.
- Collagen accounts for 40%-70% of the dry weight of cartilage matrix.
- Type II collagen makes up 90%-95% of the collagen in hyaline cartilage.
- Type II collagen forms a fibrillary meshwork that provides tensile strength and shape.
- The amount of water and other constituents in cartilage varies depending on age and location.
