The adrenal medulla is the part of the brain responsible for the release of adrenaline, when the adrenaline is released into the blood, the SAN is stimulated to work faster and increase your heart rate, this happens when playing sport or during your fight or flight response.
However, the heart is not controlled by your brain as it is a myogenic muscle (self-exciting) this means that if you were to remove the heart from a body it would continue to beat. The sino-atrial node is responsible for the excitation of the heart. :)
Hope this helps.

∙ 14y agoThe heart rate is usually controlled by the muscles and the lungs and how fast it drains in energy and oxygen, so the brain only makes the choice to make the heart rate up by the cerebral hemispheres. The cerebellum regions controls motor movement to raise the blood pressure and heart rate and they have to work normally together to control the heart rate.

What part of the controls heart rate?
the medulla oblongata which is in the brain
Part of the brain that controls your heart and lungs?
The cerebrum
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 connects to the heart and adjusts its speed according to the body's demands?
That's not such an easy question to answer, technically there is no "one thing" that controls the function alone. The heart is stimulated by electrical pulses which make it beat (which is part of the reason defibrillators work), these signals come from nerves connected to a certain part of the brain. I'm no medic but I do believe the "Hypothalamus" regulates a lot of your body's functions like body temperature. But then again, that is not a complete answer because there is another portion of the brain that controls fear specifically and commands the heart to beat faster in the "fight or flight" response. To put it into perspective there is an entire SYNAPSE of regulatory functions done by the brain and they overlap so much that learning how to be a brain surgeon is one of the most demanding jobs out there.
Connect the brain to the spinal cord and controls involuntary actions such as breathing blood pressure and heartbeat?
The part of the brain stem that controls heartbeat and breathing is called the medulla.
Which part of your brain controls involuntary activities such as breathing and heart beat?
Brain stem.
What part of the brain controls body function?
The second largest and important part of the brain, i.e Cerebellum controlls almost all body functions like heart beat,respiration,digestion..
What part of the controls heart rate?
the medulla oblongata which is in the brain
Part of the brain that controls your heart and lungs?
The cerebrum
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.
Which part part of the brain stem controls respiration and heart rate?
Medulls Oblongata
Which part of the brain function of the breathing and heart rate?
The brain stem controls these functions
What is more important Heart or Brian?
Both are very important.DETAILS-THE HEART: Some would say the heart is more important because it pumps blood to all parts of the body, including the brain. Without the blood in the brain, the brain would not be able to control involuntary activities such as heart beat. Basically, the brain needs the heart to pump blood to it.THE BRAIN:There is one part of the brain that controls involuntary activities such as heart beat. (The name of that part is the medulla) Without the medulla, the heart would never be able to pump blood to other parts of the body. Even though, you still need the heart to pump blood to the brain to let it function and control.OPINION-In my opinion truly, I think the heart is the most important because of the latest technology, machines are able to act like medullas and control heart beating. But, in order to live a wonderful life, both organs the heart & the brain are needed. :) DEFINITIONS-Involuntary activities- actions that the body cannot control, it just happens. (examples: breathing, digesting, heart beat.)Medulla- a part of the brain that connects the spinal cord to the brain. It controls involuntary activities.(located on the bottom of the brain and is the smallest part of the brain.)
What does the brain?
The brain controls the human body. I don't know if the answer above is supposed to be sarcastic, or just someone who doesn't know and wanted to add something anyway. That is an incredibly useless answer. In part, the brain controls movement of all body parts, temperature, heart beat, interprets feeling and pain, breathing, when you sleep it regulates breathing and controls the heart, and does much more, but since I'm not a doctor, that is about all I know.
What are the most importent parts of the brain?
Q - What is the most important part of the brain?A - This answer is opinionated based on facts.Probably the medulla because it is the part of the brain that controls involuntary activities such as breathing, heart beat, & digestion. It also contacts with the spinal cord and spinal nerves. :)*Other parts of the brain include-Cerebrum,Cerebellum.

What part of the brain located at the base of the Cerebrum Controls involuntary movement such as the beating of the heart?
The medulla oblongata.
