The brain is soft tissue enclosed in hard bone, the skull. When the head is hit with force, it cuases the brain to hit the skull causing a "bruise' or concussion.
Chances are you hit your head.
Bumps are caused by swelling beneath the skin. However, not all head injuries go only "out." It is possible to bruise and damage the brain, causing internal swelling. That is called acute brain trauma. It is what killed Natasha Richardson.
Yes, this is called a concussion. When you get hit in the head your brain can sometimes hit the inside of your skull which causes a concussion or after shock.
Concussion
A concussion is basically a bruise on your brain. If you hit your head hard enough, (not that I'm saying you should) your brain can move and hit the inside of your skull. Since the brain is very sensitive, it bruises if it even touches the inside of your skull. Luckily, your brain has proective fluid inside your skull to prevent a concussion. yo mama is going to take u 2 the hospital if u get one

Depends on how hard the 'bumping'. Simple hits on a flat side of a door or desk would not cause brain damage. If you hit the corner, it still wouldn't cause B.D. but it would certainly cause more outer damage, bruise, cuts etc. The only way to cause brain damage would be to hit your head with tremendous force that your brain actually moves within your skull, as might happen in a car accident, a fall or repeated hits to the head, playing football for example.
Yes. If you hit your head hard enough you can die.
