An osteon (Haversian system) is the fundamental structural unit of compact bone. It consists of:
Central Canal: Also known as the Haversian canal, it contains blood vessels and nerves supplying the bone tissue. Lamellae: Concentric rings of bone matrix surrounding the central canal, providing strength and resilience. Lacunae: Small spaces between lamellae, housing osteocytes. Canaliculi: Tiny channels connecting lacunae, allowing nutrient and waste exchange between osteocytes and blood vessels.
