The tissue cells reproduce and cover cuts, and for bones it is basically the same.

injuries to the skin heal faster than injuries in the brain because of cell division. When your skin cuts it heals faster then when something happens to your brain because your skin cells wear out quickly, so they need to be replaced often. That's why it is faster to heal than injuries to the brain :)
Injuries in the brain do not heal because brain cells cannot grow back. On the other hand body cells (skin) do grow back.
Bone injuries heal very quickly because bone has a lot of direct blood flow. This direct blood flow delivers the nutrients needed to heal an injury.

The neurons in the brain and else where do not normally regenerate. Skin cells do regenerate.
The same thing that happens to people with other injuries.
