What is an electrical knife?
I have an electric knife. They are very useful when cutting things like roasts, turkeys and hams. Here is a site on electric knives http://www.amazon.com/b?ie=UTF8&node=3737391
What is a reference node and how is it used in the analysis of dc circuits?
It is the ground node. You need to find all extraordinary nodes when using node-voltage analysis; choose one to be ground. It can be selected arbitrarily.
What is the electrical pathway of the heart?
It goes thoughSA nodeAV nodeBundle of HisPurkinjeAtria, av bundle, av node, sa node, perkinje fibers, ventriclesAVN - sinoartial nodeSAN - artioventricular nodeLA - left atriumLV - left ventricleLBB - left bundle branchRA - Right atriumRV- Right ventricleRBB - right bundle branchIVC - Inferior vana cavaPA - pulmonary arteryPV - pulmonary veinSVC - superior vena cava
What is node in electronics?
Node is Actually is nothing you can consider its as point where the Current (Ampere) Actually Get Distributed in Two or more ways .. where every get current divided that point will be know as Node
What law states that the sum of all currents entering a node must equal the sum of all currents leaving that node?
Kirchhoff's Current Law
What is a atrioventrical node?
The atrioventricular node is a part of electrical control system of the heart that co-ordinates heart rate.
What represents the time it takes for an electrical impulse to travel from the sa node to the av node?
P-R interval
What are the pathways through the body for electrical impulses?
in what order do the structures of the neuron carry the electrical signal?
Nodes in the heart?
The nodes in the heart control the hearts electrical system. The nodes are known as the sinoatrial node and the atrioventricular node.
What causes heart beat?
cancer and exercise
Depolarization of the SA node occurs during which phase?
SA node: P waveUnder normal conditions, electrical activity is spontaneously generated by the SA node, the physiological pacemaker. This electrical impulse is propagated throughout the right atrium, and throughBachmann's bundle to the left atrium, stimulating the myocardium of both atria to contract. The conduction of the electrical impulse throughout the left and right atria is seen on the ECG as the P wave. As the electrical activity is spreading throughout the atria, it travels via specialized pathways, known as internodal tracts, from the SA node to the AV node.
What delays the electrical impulses for the muscle to contract?
Atrioventricular (AV) node
Why electrical impulse start in senatorial node?
Coz they iz ard
What first causes the sinoatrial node to begin in a fetus' heart?
The sinoatrial node is a part of the electrical system of the heart. The development of the sinoatrial node is from the sinus horn myocardium in fetal development.
What is the term given to to the point where two opposite electrical currents meet?
node Any number of currents can meet at a node, not just two.
What is the medical term meaning natural pacemaker?
The sinoatrial node, abbreviated SA node, is the natural pacemaker. The SA node is a specialized collection of cells in the right atrium that can depolarize autonomously and do so on a regular basis. It is a bundle of neurons which 'fire' an electrical impulse at regular intervals, causing the heart muscle to contract. After the sinoatrial node has fired, the electrical impulse is sent to other nodes within the heart which then fire in a sequence that produces the heart beat.Sinoatrial node, SA Node
What is the sinoatrial node?
The sinoatrial node and the atrioventricular node controls the Cardiac Cycle- The Sinoatrial node is often called the Pace maker.The sinoatrial node is located in the wall of the right atrium. The Sinoatrial node emits a wave of electrical activity which reaches both Atria which causes them to contract, the wave of electrical activity is prevented from reaching the ventricles by the atrioventricular septum.Eventually the electrical activity will reach the Atrioventricular node which is situated between the atria.The Atrioventricular node conveys this along specialised muscle fibres called The Bundle of His.The bundle of his fibres release this electrical activity at the apex of the heart which causes both ventricles to contract at the same time.
