The impulse starts in the right atria in the sinus node, then travels through the intratrial fibers for atrial contraction, then travels down to the the av node where it is delayed, then travels down through the bundle branches to the purkinjee fibers to the ventricular myocardium for contraction.
SA node, AV node, bundle of His, bundle branches, and Purkinje fibers.
SA node to av node to av bundle to right and left bundle branches to purkinje
yes moving objects have impulse
Both require motor neurones to carry the nerve impulse to the effector in order for the muscle to contract carry out an action.
Fertilization takes place, Zygote divides, Implantation occurs, Gastrulation begins, and Heart forms.
most geological events occurs where there is active plate tectonic events
In liquids and solids, the heat conduction occurs through the valance electrons of the material. When you have a gas, most of the heat is conducted through radiation. When you conduct heat through a vacuum, it's all by radiation.
The bundle of His and the Purkinje fibres are part of the conduction system of the heart. In order to pump blood around the body, the heart muscle must contract (atria first to fill the ventricles, then ventricles contract to send the blood around the body.) The conduction system starts in the sinoatrial node (SA node) which is also known as the hearts natural pacemaker and is located at the top of the right atrium. The impulse is then sent to the atrioventricular node (AV node) located by the junction between the atria and ventricles. The next part of the conduction system is the bundle of His which sends the impulse from the atria to the ventricles. The purkinje fibres then spread through the ventricles. As the impulse passes through each part of the conduction system, that part of the heart is excited and the heart muscle contracts, which gives the pumping action of the heart.
each part contracts in a specific order. Contraction of the muscle is triggered by an electrical impulse. These electrical impulses travel through specialized cells that form a conduction system. Following this pathway ensures that contractions will
SAN >internodal pathway> AVN> AV/Hiss bundle> bundle branches> purkinje fibres
We have sympathetic and parasympathetic nerves. When we are fightened or scared, sympathetic nerves trigger impulse into the brain in order to release adrenaline. This adrenaline makes the heart beat faster because more oxygen is required. This helps us cope from stress.After a while parasympathetic nerves send impulse to reduce the release of adrenaline and the heart starts beating normally

Because, conduction is the transfer of heat flow fro one object to another. So that means they must touch to make conduction occur.
Two objects must be touching and it has to transfer heat
As with all inline four cylinders, The firing order is 1342.
touch-stimuli-receptor-impulse
Heart of the Order was created in 1986.
the correct order is: pharynx, larynx, trachea, bronchus, bronchioles, alveoli
When the presence of all waves is observed in the electrocardiogram, and these waves follow the order defined alphabetically, the heart is said to show a normal sinus rhythm, and impulses may be assumed to be following the regular conduction pathway
