Why is injury to the medulla oblongata usually fatal?
Injury to the medulla oblongata may result in a number of sensory-related problems. Non-fatal complications include numbness, paralysis, difficulty swallowing, acid reflux, and lack of motor control. But because the medulla also controls vital autonomic functions such as breathing and heart rate, damage to this area of the brain can be fatal.
What would happen if TH medulla oblongata was damaged?
Your medulla oblongata is located at the base of your brain, where the brain stem connects the brain to your spinal cord. It plays an essential role in passing messages between your spinal cord and brain. If your medulla oblongata becomes damaged, it can lead to respiratory failure, paralysis, or loss of sensation.
What does damage to the medulla cause?
It is involved in muscle movement, autonomic body functions, and excitatory reactions. Damage to the medulla oblongata can cause several functions of the body to be thrown off and even death. Because cranial nerves run through this section of the brain injury there can cause several sensory problems.

What happens if you have a stroke in the medulla oblongata?
A medullary stroke happens in the medulla oblongata, which is located on the brain stem. This part of your brain transfers messages from the brain to the spinal cord and is responsible for many of your body's involuntary functions. A medullary stroke can cause serious symptoms like paralysis and coordination problems.
