**Note 3:** **Periosteum**
* Periosteum is a fibrous membrane that wraps the outer surface of bones.
* Cortical bone is the dense compact outer layer of the bone.
* Trabecular, cancellous, or spongy bone (spongiosa) is a porous network of tissue filling the interior of bone, decreasing weight and allowing room for blood vessels and marrow.
