Study Notes
Cartilage Matrix
- The extracellular matrix of cartilage is maintained by fibrocytes.
- Nutrients and oxygen diffuse through the matrix to reach chondrocytes.
- The matrix is responsible for the hard consistency of cartilage.
- Cartilage is rich in collagen fibers, type III.

Description
This quiz focuses on the structure and function of the cartilage matrix. It covers the role of fibrocytes, the diffusion of nutrients and oxygen to chondrocytes, and the composition of the matrix, which is rich in collagen fibers. Test your understanding of how these elements contribute to the properties of cartilage.
