The brainstem is like the control center of our body. It helps manage important functions that keep us alive. The brainstem has three main parts: the midbrain, pons, and medulla oblongata. Each part does something special to help us live.
Breathing Control:
The medulla oblongata helps us breathe. It has centers that start and control our breathing pattern. It reacts to how much carbon dioxide (CO2) and oxygen (O2) is in our blood. For example, if there is more CO2, our breathing can speed up by about 30% to make sure we get enough oxygen.
Heart and Blood Control:
The brainstem also helps with our heart and blood. The medulla oblongata controls how fast our heart beats, our blood pressure, and how big our blood vessels are. When these centers don’t work well, it can cause serious problems, like low blood pressure, especially in older people. This affects about 20% of those over 60.
Quick Reactions:
The brainstem helps us react quickly in important situations. For example, when we cough, that action starts in the brainstem. Studies show that about 90% of our automatic reactions to things around us come from the brainstem. This shows just how important it is.
Sleep and Awareness:
The brainstem also plays a role in sleep and wakefulness. A system in the brainstem called the reticular activating system (RAS) helps keep us awake. If the RAS has problems, it can cause sleep issues for about 30% of adults worldwide.
Processing Sensory Information:
The brainstem acts like a hub for messages from our body to the higher parts of the brain. Most of our sensory information, about 80%, passes through the brainstem before going to the thalamus, where it gets processed further.
In short, the brainstem is crucial for controlling breathing, heart functions, quick reflexes, sleep, and processing what we sense. It plays a key role in keeping our body balanced and functioning well.
