What are lamellae and Osteons?
Osteons are cylindrical structures that contain a mineral matrix and living osteocytes connected by canaliculi, which transport blood. They are aligned parallel to the long axis of the bone. Each osteon consists of lamellae, which are layers of compact matrix that surround a central canal called the Haversian canal.
What is the difference between compact bone and cancellous bone?
The key difference between compact and cancellous bone is their structure. Compact bone is the harder outer shell of the bone while cancellous bone is the inner porous, less dense layers of the bone. Bones are important components in assisting movement and granting a shape to the body.
