What else can I help you with?
Where in the heart is the heart beat controlled?
Simple answer is sinus node
What especial equipment is connected to the heart to make it beat?
When the SA node in your heart stops functioning properly, then you have to receive a pacemaker, which will take the place of the SA node and set your heart beat for you.
How does the heart control it's beat?
stimulation from the Sino Atrial node: SA node
How does control of the heart beat occur?
the Sino Atrial Node (SA Node) is the pace maker of the heart that receives singles from the brain.
How is heart beat regulated during exercise?
The rate of the heart beat is regulated by the SA node (SinoAtrial Node/aka the Pacemaker). It determines how fast the heart pumps by sending electrical signals faster or slower to the rest of the heart.
How would damage to the sinoatrial node affect the heart's function?
The heart wouldn't beat at a constant rate.
Is often called the pacemaker of the heart?
It regulates a heartbeat in a weak heart by sending an electric charge at intervals to make it beat.
What initiates the heartbeat?
By generating electrical impulses.By: isamarThe individual cells in a heart actually can beat on their own without any nervous stimulus. However, the cells have to beat together to have a heart that functions the right way. There is a conduction system in the heart made of specialized heart cells that make the rhythm. There are two main "nodes" called the SA node and AV node. The SA node starts the beat. The AV node is a sort of back up for the SA node. There are other special heart cells that made up of special fibers that transmits the signal through out the walls of the heart.
Where do action potentials associated with heartbeat regulation originate?
Action potentials associated with heartbeat regulation originate in the sinoatrial (SA) node, often referred to as the heart's natural pacemaker. The SA node generates electrical impulses that spread through the heart, coordinating the contraction of the atria and the ventricles. This rhythmic action potential initiation in the SA node is crucial for maintaining a regular heartbeat.
What are the group of cells that ajust the heart beat?
The group of cells responsible for adjusting the heart rate are known as the sinoatrial node (SA node) and the atrioventricular node (AV node). The SA node generates the electrical impulses that initiate each heartbeat, while the AV node delays the impulse to allow the atria to contract before the ventricles. Together, these nodes help regulate the heart rate and ensure proper coordination of heart contractions.
What causes heart beat?
cancer and exercise
Why sa mode known as peacemaker?
the SA node (sinoatrial node) stimulates the heart to beat @ a particular rate. when this node causes the heart to beat too fast or too slow or irregularly, a pacemaker (a small mechanical device) is surgically implanted under the skin of the chest to regulate the heartbeat.
