Question

Quizplus · Accepted Answer

Osteons, also known as Haversian systems, are the functional units of compact bone. They consist of a central canal that houses blood vessels and nerves, surrounded by concentric layers of mineralized extracellular matrix called lamellae. The lamellae are interconnected by small channels called canaliculi, which allow for the exchange of nutrients and waste products between the osteocytes (bone cells) located in lacunae (small cavities) within the lamellae. Trabeculae are found in spongy bone, not compact bone.
