Osteoclasts
The cylindrical units inside compact bone
Provides a pathway for nutrients to get to cells
Osteons
Inside the osteon that contains blood blood vessels and nerves
Central canal
Series of cylinders formed around the outside of the central canal.
Forms the shape of the osteon
Lamellae
‘Lakes’ for osteocytes.
Thin layers of ecm matrix
Lacunae
Channels for nutrients to travel to osteocytes through the ecm
Canaliculi
Cancellous bone is made up of these branches
Trabeculae
