Brainstem lesions decrease heart rate variability. Neurologia. 2000 Apr;15(4):158-63 This article showed that lesions of the medulla oblongata cause heart rate problems. However, total heart rate control occurs in scattered regions of the entire brainstem including the pons and mesencephalon.
The medulla oblongata is found in the brain stem and holds the pathways of communication between the spinal cord and the various sections of the brain. The medulla is used to conduct sensory information from one side of the brain to the other, which in turn influences the opposite side of the body.
This part of the brain stem controls the heartbeat and the rhythm of breathing, and regulates the size of blood vessels. Minor operations of the medulla oblongata deal with the functions of swallowing, vomiting, coughing, sneezing, and the hiccups.

What does brainstem have to do with heart rate?
The brainstem has a part named the medulla oblongata, which controls the natural, life necessary functions, such as heart beat. This is commonly believed to be the only part of the brain that perople need to survive.
What part of the nervous system that regulates heart beat digestion?
Parasympathetic division
What part of the human brain controls breathing heart rate and respiration?
The medulla oblongata, located in the brainstem, controls breathing, heart rate, and respiration. It regulates these vital functions automatically without conscious effort.
What part of the brain regulates body movement attention sleep and alertness?
The pons is the part of the brain that regulates body movement, attention, sleep, and alertness. The pons is the part of the brainstem that links the medulla oblongata and the thalamus.
What part of the hind brain regulates body movement attention sleep and alertness?
The brainstem, specifically the reticular formation, plays a crucial role in regulating body movement, attention, sleep, and alertness. It helps control vital functions like heart rate and breathing, and plays a role in maintaining consciousness and arousal.
Explain the expression brainstem as an anatomical term?
The brainstem is the lower part of the brain connecting the cerebrum with the spinal cord. It controls basic life functions such as breathing, heart rate, and blood pressure. Additionally, it regulates essential bodily functions like swallowing, digestion, and motor control.
Which part of the brain is the survival center?
The brainstem, specifically the medulla oblongata, is often referred to as the survival center of the brain. It regulates essential functions like breathing, heart rate, and blood pressure, which are necessary for survival.
What center in the brain regulates the rate of the sinoatrial node?
The medulla oblongata in the brainstem regulates the rate of the sinoatrial node, which serves as the heart's natural pacemaker. It controls heart rate by influencing the parasympathetic and sympathetic nervous systems.
What part of the brain controls heart rate blood pressure and digestive system?
The autonomic nervous system, specifically the medulla oblongata, within the brainstem, controls essential functions such as heart rate, blood pressure, and digestion. This area regulates these functions automatically, without conscious effort.
Which part of the brain controls your heartbeat?
The brainstem, specifically the medulla oblongata, regulates the heartbeat by coordinating signals between the heart and the brain. It contains the cardiac and vasomotor centers that control heart rate and blood pressure.
What is the heart's control center called?
Medulla oblongata, the lower part of the brainstem.
Which part of the brainstem houses the reflex centers for respiration and cardiovascular functioning?
The medulla oblongata, located in the lower part of the brainstem, houses the reflex centers for respiration and cardiovascular functioning. It plays a crucial role in controlling vital functions such as breathing, heart rate, and blood pressure.
