What bones are spongy?
In respect to this, what is spongy bone composed of?
Spongy (Cancellous) Bone Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.
Beside above, what does spongy bone look like? Unlike compact bone that is mostly solid, spongy bone is full of open sections called pores. If you were to look at it in under a microscope, it would look a lot like your kitchen sponge. Pores are filled with marrow, nerves, and blood vessels that carry cells and nutrients in and out of the bone.
Also to know is, do all bones have spongy bone?
Whereas compact bone tissue forms the outer layer of all bones, spongy bone or cancellous bone forms the inner layer of all bones. Spongy bone tissue does not contain osteons that constitute compact bone tissue. Instead, it consists of trabeculae, which are lamellae that are arranged as rods or plates.
Does spongy bone have periosteum?
Spongy bone is sometimes called cancellous bone or trabecular bone. The outsides of all the bones of the body are covered with a layer of irregular dense connective tissue proper called the periosteum. The medullary cavity, live the spaces in spongy bone, is filled with bone marrow. Figure 6.2.
