Spongy bone microstructure, illustration 插畫檔

Illustration showing the microstructure and cellular composition of cancellous bone. The left panel presents a cross-sectional schematic of bone tissue, demonstrating the dense outer cortical bone and the inner spongy cancellous bone. The right magnified panel details the microscopic architecture of the trabeculae, where osteocytes reside within lacunae and interconnect via canaliculi to facilitate metabolic exchange. The trabecular surfaces are lined with osteoblasts responsible for bone matrix synthesis and mineralization, alongside osteoclasts that mediate bone resorption and remodelling. The interstitial matrix fills the spaces between the bone lamellae to maintain structural integrity
