Chondrocytes in lacunae embedded in a glassy type-II collagen matrix. Lines articular surfaces + forms respiratory rings; avascular.
Labeled regions (3)
- 1Chondrocyte in lacuna
Cell occupies a space (lacuna) within the matrix; pairs = isogenous groups (recent division).
- 2Territorial matrix
Densely basophilic halo of GAGs around each chondrocyte.
- 3Perichondrium
Dense connective tissue surrounding cartilage; source of new chondroblasts.
