Cancellous bone or spongy bone, [12] [11] also known as trabecular bone, is the internal tissue of the skeletal bone and is an open cell porous network that follows the material properties of biofoams. [13] [14] Cancellous bone has a higher surface-area-to-volume ratio than cortical bone and it is less dense. This makes it weaker and more flexible.

Demineralized bone matrix (DBM) is allograft bone that has had the inorganic mineral removed, leaving behind the organic "collagen" matrix. It was first discovered by Marshall Urist in 1965 that the removal of the bone mineral exposes more biologically active bone morphogenetic proteins . [ 1 ]
The bone matrix can store calcium and is involved in calcium metabolism, and bone marrow can store iron in ferritin and is involved in iron metabolism. However, bones are not entirely made of calcium, but a mixture of chondroitin sulfate and hydroxyapatite, the latter making up 70% of a bone. Hydroxyapatite is in turn composed of 39.8% of ...
Artificial bone refers to bone-like material created in a laboratory that can be used in bone grafts, to replace human bone that was lost due to severe fractures, disease, etc. [1] Bone fracture, which is a complete or partial break in the bone, is a very common condition that has more than three million US cases per year.

The Haversian canal contains the bone's blood supplies. The boundary of an osteon is the cement line. Each Haversian canal is surrounded by varying number (5-20) of concentrically arranged lamellae of bone matrix. Near the surface of the compact bone, the lamellae are arranged parallel to the surface; these are called circumferential lamellae.
Bone is a form of connective tissue found in the body, composed largely of hardened hydroxyapatite-containing collagen.In larger mammals, it is arranged in osteon regions. . Bone matrix allows mineral salts such as calcium to be stored and provides protection for internal organs and support for locomoti
Ossein is the organic extracellular matrix of bone, which is made of 95% collagen.This substance is used in industry for the production of gelatin and bone glue.. In the early 20th century, bones were found to consist of three types of proteins: ossein (collagens), osseomucoid (proteoglycans) and osseoalbuminoid (). [1]
