What is the central canal in an osteon responsible for?

• Storing calcium

• Producing red blood cells

• Housing blood vessels and nerves

• Connecting osteons

What are the concentric layers around the central canal called?

• Lacunae

• Lamellae

• Canaliculi

• Osteocytes

What is found within the lacunae?

• Canaliculi

• Nerve endings

• Osteocytes

• Blood vessels

What is the primary function of canaliculi?

• To store fat

• To transport nutrients to osteocytes

• To connect different bones

• To produce bone matrix

How do nutrients reach the osteocytes in the lacunae?

• Through the central canal

• By diffusion through the bone matrix

• Directly from the blood

• Via the canaliculi
