Brain Healing: This is a picture of brain cells. There is a lot of controversy between the brain healing itself and not. There is some research that the brain tries to heal itself when damaged. Apparently brains can make new nerve cells by a process called neurogenesis. This is picture that shows neurogenesis. First the cells form. Half of the cells formed die off. Some of the cells become support cells. Only a small percent are stem cells that can become nerve cells. There is now research on new nerve-cell growth and how it can be maximized and directed toward the most damaged areas of the brain. There are rehabilitation therapies that stimulate sprouting of existing nerve cells, causing them to make connections to other nerve cells. The brain can recruit surviving parts to take over the functions of the damaged areas. Bone Healing: …show more content…

When a bone is broken the following things happen: a blood clot forms around the break. Inside the blood clot, special cells called phagocytes begin cleaning bone fragments and killing any germs which might have gotten in around the break. Phagocytes are part of the immune system. Next, a soft callus made mostly of collagen is created around the fracture by another special group of cells called chondroblasts. This stage can last anywhere from 4 days to 3 weeks. A hard callus forms next as osteoblast cells create new bone, adding minerals to make it hard. This stage typically begins 2 weeks after the break, and ends somewhere between the 6th and 12th week. Lastly, the bone is remodeled. Special cells called osteoclasts break down extra bone around the fracture until it's completely healed and returned to its original shape. This stage typically begins 2 weeks after the break, and ends somewhere between the 6th and 12th
