Within the compact bone are many layers of cancellous (say: KAN-sell-us) bone, which looks a bit like a sponge. Cancellous bone is not quite as hard as compact bone, but it is still very strong. In many bones, the cancellous bone protects the innermost part of the bone, the bone marrow (say: MAIR-oh). Bone marrow is sort of like a thick jelly ...
Bone Basics. Importance of Bones. Bones and the skeleton play many important roles in the body, including In general, bones are made up of spongy, mesh-like cancellous bone covered by hard, compact cortical bone. Bone marrow is found within the spongy bone at the center of many bones.
Bone regeneration process may improve effectively and rapidly when stem cells are used. In addition, the role of mesenchymal stem cells for bone repair/regrowth in the tissue engineering field and their recent progress in clinical applications will be discussed.
Larynx: an enlarged structure on the trachea. If you cut it open, you can see the vocal cords inside. Thymus Gland: an endocrine (hormone-secreting) gland that helps regulate the immune system. It’s a large, spongy structure covering the ventral surface of the trachea, extending up along either side, and also resides over the heart.

Bone's ability to change its morphology in response to load is widely attributed to osteocytes. A study of fish shows that bone can respond to load even in the absence of osteocytes, using a molecular mechanism that is conserved across vertebrates, albeit with different cellular effectors.
