Bone is a secondary support tissue. It develops on the base of a preexistent primary scaffold, built up by connective tissue or by cartilage. Bone formation depends on the magnitude of the elastic deformation, due to loading. The skeletal organ "bone" reacts to the actual stress like a feedback system: high stress stimulates new bone formation and incorporation of mineral salts; low stress leads to bone resorption and mobilization of mineral salts. The result of extreme stress is bone resorption (stress fractures, pseudocysts). The radiological density and architecture of the spongy bone reflect exactly the direction and local magnitude of stress.
骨是一种次级支撑组织。它在由结缔组织或软骨构建的先前存在的初级支架基础上发育。骨的形成取决于由于负荷引起的弹性变形程度。骨骼器官“骨”像一个反馈系统一样对实际应力做出反应：高应力刺激新骨形成和矿物质盐的沉积；低应力导致骨吸收和矿物质盐的动员。极端应力的结果是骨吸收（应力性骨折、假囊肿）。松质骨的放射学密度和结构准确反映了应力的方向和局部大小。
