Step 1 : Introduction to the question "2. Marble Bone Disease causes the bones to become solid all the way through, causing a loss of which of the following?"
...1. Tendons 2. Bone marrow 3. The brain 4. Ligaments Bones are constantly being broken down and reformed to allow for the body's need for calcium. In the condition known as Marble Bone Disease this natural reformation causes the hard outer bone to reform in the area occupied by the softer more porous inner bone which houses the marrow. The bones become very dense and movement is impeded. When it occurs in adults, which is the most common scenario, it causes pain, bone fracture and difficulty in healing. A more deadly form occurs in children causing additional problems including deafness, blindness, seizures, pain and usually death. Treatment is aimed at easing the symptoms as there is no cure.
