The Haversian System, also known as the osteon, is the fundamental structural unit of compact bone. It consists of concentric layers of bone matrix, called lamellae, surrounding a central canal that contains blood vessels and nerves. This organization allows for efficient nutrient delivery and waste removal, supporting the bone's strength and resilience. Each Haversian System is interconnected by tiny channels called canaliculi, which facilitate communication between bone cells, or osteocytes. This intricate network ensures that the bone remains healthy and can adapt to mechanical stress, playing a crucial role in the overall function of the skeletal system.
