Why is trauma to the base of the brain often much more dangerous than that to the frontal lobe?

Why is trauma to the base of the brain often much more dangerous than trauma to the frontal lobe?
The medulla oblongata is the lower portion of the brainstem. It functions primarily as a relay station for the crossing of motor tracts between the spinal cord and the brain.It also contains the respiratory, vasomotor and cardiac centers, as well as many mechanisms for controlling reflex activities such as coughing, gagging, swallowing and vomiting. It controls most of the autonomical (automatic) functions of the body.
It is closer to where the brain connects to the spinal column, and can cause organ failure, and paralyzation.
the base of the brain is your brain stem and your brain stem is what connects the brain to your spine if you break or hurt that there might is a good chance you will have some problems functioning, feeling, moving, a lot of stuff could happen
The base of the brain contains the centers that control essential reflexes involved with breathing and heartbeat. Also, the entire communication of the brain to the body below the neck happens through the brainstem. Damage that, and the whole body suffers.
Because it's closer to the spine.
Because the base supports basic, crucial functions, like breathing, physiognomical needs, and so on. And the front is respondent for logic, memory and so on. So if you hit yourself into the Back of your had too strong the part of your brain, the part of your brain that, say, controls breathing might be injured, and you will die. You can hit yourself into the front of your head, and only loose memory.
the brainstem - where vital functions - heart rate, respiration, temperature control are all located in that area, that's true, but the real problem is that when there's injury there and swelling, there's not enough room for the carotid arteries, it those get pinched, and if the circle of willis is not complete - as it it should be - then death is fairly rapid. if the circle is complete then the patient may get enough colateral supply from the basilar artery until the swelling goes down. If I recall correctly - about 25% of us do not have a complete circle.
