The simplest assumption about the explosion of Kennedy's head is that an exiting bullet ripped a large defect and the bullet and brain matter exited at the defect. In fact, the process was a bit more complicated.
When a bullet hits human tissue, it loses a lot of energy in under a millisecond, and that energy has to go somewhere. In fact, the energy creates a pressure cavily in the tissue almost as though a small stick of dynamite had been set off within the body.

You can click here to see a different clip of the same thing happening. Both clips are from the 1988 NOVA documentary.
