The cells in the epidermis are more compact because they are at the surface and create a barrier. The dermis cells are looser because they are newly forming. The cancellous bone contains peristerum, developing marrow of the cancellous bone, and the trabeculae of the cancellous bone. The compact bone has a perforating canal, an interstitial Lamella, the Osteon, and a central canal. Cancellous bone contains the outermost layer called the periostium, essential for bone nutrients, growth, and repair. Contains trabeculae of cancellous bone, this is a network of fine, irregular plated of bone. Finally, in the developing bone marrow, active bone is dominated by maturing erythrocytes, also containing primitive stem cells. Compact bone contains the lacuna of compact bone; this is within the matrix and
