Accepted Answer

The spaces within the spongy bone, also known as trabecular bone, are filled with bone marrow. This bone marrow can be either red or yellow depending on its function and location within the bone. Osteons, lacunae, and canaliculi are all structures found within compact bone, which is denser and makes up the outer layer of bones.
