Here's a breakdown:

* Chondroblasts: These are specialized cells responsible for producing and maintaining cartilage, a type of connective tissue.

* Cartilage matrix: This is the extracellular material surrounding chondroblasts. It's made up of:

* Collagen fibers: Provide strength and flexibility.

* Elastin fibers: Provide elasticity.

* Proteoglycans: Attract water, giving cartilage its resilience and ability to absorb shock.

Once chondroblasts become surrounded by the matrix they produce, they mature into chondrocytes. Chondrocytes continue to maintain the cartilage matrix, but at a slower rate than chondroblasts.
