The brainstem has an ectodermal origin and is composed of 4 parts: the diencephalon, mesencephalon, pons, and medulla oblongata.

What is the main function of the brainstem?

Brainstem, area at the base of the brain that lies between the deep structures of the cerebral hemispheres and the cervical spinal cord and that serves a critical role in regulating certain involuntary actions of the body, including heartbeat and breathing.

What are the three main functions of the brainstem?

The brainstem has many basic functions, including regulation of heart rate, breathing, sleeping, and eating. It also plays a role in conduction. All information relayed from the body to the cerebrum and cerebellum and vice versa must traverse the brainstem.

Can the brain stem be repaired?

The brain stem is home to the most basic life functions, and the resulting damage can be devastating. However, it is possible for a person with a brain stem injury to at least partially recover by using the brain’s natural plasticity.

What is the medulla responsible for?

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. It’s also essential for regulating your cardiovascular and respiratory systems.

Does medulla oblongata control anger?

This is not entirely true though; the more complex emotion of anger primarily derives from activity in the hypothalamus and amygdala.

Can a person live with brain stem damage?

When an accident causes brain stem damage, the affects can be devastating. In fact, destruction of the midbrain, pons, or medulla oblongata causes “brain death”, and the unfortunate victim of the injury cannot survive.

How do you know if your brain stem is damaged?

Symptoms of a brain stem injury include:

1. Abnormal sleeping patterns.
2. Insomnia.
3. Dizziness.
4. Nausea or vomiting.
5. Balance issues.
6. Inability to cough or gag.
7. Difficulty eating, drinking, or swallowing.
8. Slurred speech.

Why is damage to the brain stem life threatening?

Heartbeat and breathing can cease, causing death. The brain-stem can become compressed due to swelling, leading to hemorrhaging and stroke. This may result in speech impairment, breathing difficulties, including sleep apnea and difficulty swallowing. In acute cases, there may be personality changes and memory loss.
