Final answer:
The haversian and lamellar bone systems are both involved in the nutrition of the osteocytes. The haversian system consists of osteons, which are cylindrical structures made up of concentric rings of calcified matrix called lamellae. The osteocytes receive their nutrition from the central canal through canaliculi.
Step-by-step explanation:
The haversian and lamellar bone systems are both involved in the nutrition of the osteocytes. The haversian system consists of osteons, which are cylindrical structures made up of concentric rings of calcified matrix called lamellae. The central canal of the osteon, known as the Haversian canal, contains blood vessels that supply nutrients to the osteocytes.
The osteocytes, which are mature bone cells, receive their nutrition from the central canal through canaliculi, which are small canals that connect the lacunae where the osteocytes are located.
