An electrical signal causes the atria to?
bubble up and popno one knowsthe signal causes the atria to contract.
The stage of the heart cycle in which the heart muscle contacts and the chambers pump blood?
The sinoatrial node depolarizes the atria and causes them to contract which tops up the ventricles with blood, the signal then moves through the atrioventricular node and then the atrioventricular bundle and into the purkinje fibres which causes the ventricles to depolarize and contract sending blood from the right ventricle to the lungs and from the left ventricle. The Atria repolarizes at the same time as the ventricles depolarize and then a fraction of a second later the ventricles repolarize and the cycle begins again.
What does the interventricle septum do?
It is a thick muscular septum, which divides the two cardiac ventricles. It also transmits the signal for contraction of ventricular muscles through 'Bundle of HIS'.
If the atrioventricular node could be surgically removed from the heart without disrupting signal transmission to the Purkinje fibers what would be the effect?
Atria and ventricles would contract at about the same time.
Is saying that a device transmits a signal correct?
Yes, it is correct
What are neurontransmitters?
a chemical that transmits a nervous systems signal across a synapse.
What is continuous signal that transmits information?
I'm not sure. what you think homie
What creates heart rate?
Heart rate is simply the number of times that the heart beats per minute. This is generated by the "pacemaker" of the body which is the signal sent from the brain to the heart's sinoatrial (SA) node. This causes the initiation of contraction of the cardiac muscle which spreads across the heart to contract the atria and ventricles in a rhythmic fashion. The number of times this signal is sent from the brain to the heart gives the heart rate.
Which part of the heart has the longest action potential?
The AV (atrioventricular node). Electrical conduction is slowed down at this node, and half the time of each action potential is spent on getting the signal through the AV node. This delay is to allow the ventricles to fill completely with blood before they get the signal to contract.
Which frequency signal does the mobile phone transmits continuously?
None, as it doesn't transmit continuously.
What is a continuous signal that transmits information?
I'm not sure. what you think homie
The chemical that transmits the signal across the neuromuscular junction is called?
Acetylcholine
