3 Questions
Which of the following statements about chondrocytes is true?
They secrete metalloproteinases.
What is the primary function of collagen in hyaline cartilage?
To give cartilage its shape
What percentage of the dry weight of cartilage matrix is collagen?
40%-70%
Study Notes
- Chondrocytes synthesize and maintain the extracellular matrix in hyaline cartilage.
- Chondrocytes can be found singularly or in clusters called isogenous groups.
- Isogenous groups represent recently divided cells.
- Newly divided chondrocytes produce the matrix material and secrete metalloproteinases.
- Water and inorganic salts give cartilage its flexibility and lubricating capabilities.
- Structural macromolecules in cartilage include collagens, PGs, and non-collagenous proteins.
- Type II collagen accounts for 90%-95% of the collagen in hyaline cartilage.
- Collagen provides tensile strength and shape to cartilage.
- The wet weight of cartilage is 60%-70% water and inorganic salts.
- The dry weight of cartilage matrix is 40%-70% collagen.
