Metachromasia showing capsular, territorial, and interterritorial maxtrix areas
ACTIVE chondrocytes show areas of basophilic cytoplasm (RER) and prominent Golgi (arrows)
Chondrocytes. Clear areas represent areas of glycogen and lipids
Trachea is lined by a psuedostratified ciliated columnar epithelium (EP). Chondrocytes (C) are visible within the mass of hyaline cartilage that make the tracheal ring. The cartilage is covered from both sides by pericondrium (P). V, blood vessel
A-pseudostratified ciliated columnar epithelium
Perichondrium (arrows) surrounds a growing hyaline cartilage.
hyaline cartilage, surrounded by perichondrium
Hyaline cartilage is surrounded by perichondrium (Peri) which consists of two layers; outer fibrous layer (F) composed of mostly collagenous fibers and fibroblasts, and an inner more cellular chondrogenic layer (CG) that gives rise to chondroblasts (CB). As newly differentiated chondroblast starts to secrete ECM they eventually became surrounded by their secretion and called condrocytes (CC).
