Spongy bone scaffold structure is conducive to the maintenance of bone shape, resist pressure, constitute most of the axial skeleton, such as the skull, ribs, spine bone.
What Does Spongy Bone Do?
Bone is a unique structure, high density of connective tissue, the structure is divided into cortical bone, cancellous bone. Trabecular bone which accounted for 20% of the human body bone mass, but constitute 80% of the bone surface. Trabecular bone mineral density lower than the cortical bone, while the elastic; cancellous bone scaffold structure is conducive to the maintenance of bone shape, resist pressure, constitute most of the axial skeleton, such as the skull, ribs, spine bone.
There are two bone; honeycomb-like trabecular bone at both ends of bone, dense cortical bone hard to focus on the backbone of support and protection that they can play the role of the central bone is the bone marrow cavity. This hollow tubular structures both portable and sturdy enough to adapt to in the motor function. The physical properties of bone mainly two aspects in terms of hardness and flexibility, because bone is a hard brittle inorganic and flexibility of the organic composition. Adult bone-containing organic compounds is about 1 / 3, inorganic about 2 / 3. Children and adolescents, bone organic matter content of more than 1 / 3, easily deformed, it should pay attention to sit, stand and walking the correct posture. When the in vivo or in vitro environment, the environment changes, the bone in the shape, structure can also be changed, called bone plasticity. For example, after fracture, bone healing and regeneration can be; manual and physical activity make bones become thick; paralyzed and bedridden patients, bone became loose.
