What is the precise amount of electrical pulses does the brain send the heart?
Damu555
The brain does not send "electrical pulses" to the heart. Electrical impulses are actually generated within the heart itself (in the SA node), which travel through several intricate pathways from the atria down to the ventricles.

What creates the electrical signal in your heart?
neural impulses from the brain
Does heart work alone?
no the heart resives an electrical signal from the brain causing the mucle to flex
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.
Does the SA node controlled by the brain require signals from the autonomic nervous system to send the impulses for the cardiac muscle to contract?
No. The nodes are automatic. They start the pulses by themselves. This is called an automatic pacemaker. They have no external nerve or hormonal control.
How does the heart keep the blood moving in the body?
The heart has an area called the sinuatrial node, often called the SA node, in the upper right atrium. The SA node is responsible for generating a never-ending series of rhythmic electrical pulses that radiate through specific electrical conduction pathways in the heart. The heart muscle contracts when stimulated by one of these electrical pulses. The SA node and the conduction pathways coordinate the timing and delivery of the electrical stimulations at various locations in the heart muscle so that the heart contractions result in a coherent and productive pumping action.For more information, follow the link below to the Wikipedia article on the electrical conduction system of the heart.
What is tremor control therapy?
Tremor control therapy is a type of treatment using mild electrical pulses to stimulate the brain. These pulses block the brain signals that trigger tremor.
What is hearing?
Your eardrums take fluctuations of the air pressure on your ears and converts them to electrical pulses, which are sent to the brain. The brain then interprets the electrical signals as different sounds.
How are electronic pulses involved in the creation of thoughts?
While we know that brain activity involves electrical pulses, no one knows -- as yet -- specifically how they relate to thought.
What is deep brain stimulation and how can I prevent it?
Deep Brain Stimulation is a procedure which is used to treat movement disorders such as Tourrett's Syndrome and Parkinson's Disease. It requires the implanting of a braun pacemaker which sense electrical pulses to the brain.
Where are the cells that make up the pacemaker?
Those cells are nerve cells, the brain sends electrical pulses down and the electricity causes the heart to beat.
What does muscles do for me?
make your body move and function. The Brain sends electrical pulses to a certain part of the body telling the muscle to contract, then you move. Your brain cant type on a key board, but it can tell your hands to.
What happens when someone's body when they are tased?
The electrical current jolts through their nervous system making the muscles tense and the electrical pulses from the brain unreadable. The process is called neuromuscular incapacitation. TASER is an acronym for the brand.
Is an epileptic fit due to a over load of electicity made by the body?
It is an unusual level of electrical activity in the brain. There is constant electrical activity in the brain. If it is disrupted or an extra amount of it happens it may affect the working of the brain temporarily and the result is a seizure.
How are your movement controlled by the nervous system?
by sending weak electrical pulses through our system. that is also one of the reasons our spine is important, because the electrical pulses are sent through it and it they stop thats when we stop being able to fully use the lower half of our body
How are signals sent from the brain to the rest of the body?
They are sent through your nervous system by electric pulses from your brain
How does the parietal work?
The parietal lobe is one of the four major lobes, regions of the cerebral cortex. This particular lobe works to process sensory information for other parts of the brain, and at its core works via the same electrical pulses the rest of the brain uses to function.
Do our brains run on binary code?
Lets just say nobody knows how the brain works deep deep down. But there are binary things in the brain, like a neuron will either output a 1 (it fires) or a zero (it does nothing) depending on the number of electrical pulses sent to the neuron
