The limbic system is positioned underneath the brain stem. It is in charge of critical life activities including breathing, heartbeat, and blood pressure. The medulla's principal job is to govern involuntary life-sustaining activities like as breathing, swallowing, and heart rate. The cerebellum is responsible for learning and memory.
The mind and body are connected: thinking patterns can have an impact on your physical health, and poor physical health can affect how you think. Mindfulness practices such as meditation help us become more aware of these connections so that we can better understand how we feel physically and emotionally.
Why is it important to know about the brain and heart? Because knowing about their relationship can help us identify problems with our hearts when other symptoms appear to be coming from the brain. Also, it is possible for the brain to damage or malfunction irreversibly due to a stroke or tumor. In this case, too, knowing about the relationship between the brain and heart can help doctors diagnose such conditions early before too much harm has been done.
What is a stroke? A stroke is an injury to the brain caused by lack of oxygen to the brain tissue. This can be due to several reasons including obstruction of blood flow to part of the brain, a cardiac arrest during which blood no longer reaches the brain, or using drugs that decrease blood pressure substantially.
It also aids in the transmission of neural impulses to and from the brain and spinal cord as part of the brain stem. It is situated at the point where the spinal cord and the brain meet. The medulla is divided into two parts: the pons and the midbrain.
The pons is a bridge between the brain and the spinal cord. It supports many important nerves and communicates with other parts of the brain through pathways called pontine tracts.
The midbrain is the middle part of the brain stem. It is about the size of a fist with fingers extending out on each side. The midbrain is responsible for controlling eye movements, certain muscles of the face, hearing, and balance. It is divided into two parts: the tegmentum and the tectum. The tegmentum lies beneath the cerebral cortex and contains nerve cells that control movement. The tectum is the back part of the midbrain and contains nerve cells that control sight.
The hindbrain is the last portion of the brain stem. It consists of three regions: the cerebellum, which is involved in learning and memory; the mesencephalon, which is involved in sensory perception; and the pons, which connects the brain to the spine.
The medulla is made up of two parts: the pons and the midbrain. The pons is a bridge between the upper part of the brain and the lower part while the midbrain is at the middle part of the brain stem.
The vagus nerve runs from the medulla down to the rest of the body where it communicates with various organs including the heart, lungs, and stomach. The vagus nerve is responsible for sending signals to these organs to function properly. If you block this signal traveling down the vagus nerve in order for you to die, then your body would not receive this message and would not stop functioning until something caused it to do so. For example, if someone were to cut off the head of a cockroach, the insect would continue to move around for some time because its brain keeps sending messages to its legs trying to have them move. This shows that the medulla oblongata is necessary for a person to live because without it they could stop living even though their brain is still working.
In addition to controlling vital functions like breathing and heartbeat, the medulla also plays a role in sensory perception, memory, and emotion.
