Definitions:

Endosteum

Membranous lining of the medullary cavity and the cavities of spongy bone.

Periosteum

Bones are encased in a thick connective tissue full of blood vessels, except where the joints are located.

Ruffled Borders

Ruffled borders are specialized structures of osteoclasts involved in bone resorption, where the bone surface is broken down and minerals released.

Osteoclasts

Bone cells that break down bone tissue, helping in bone resorption and remodeling.
