What are the pathways through the body for electrical impulses?
in what order do the structures of the neuron carry the electrical signal?
What is the correct sequence of cardiac electrical activity?
The impulses from SA node spread through out the atrial musculature in about 0.09 seconds, and parallel to it, the impulses also reach the AV node. From AV node, after a delay of about 0.12 seconds they pass to the inter ventricular septum through the Bundle of His, which soon divides into Left and Right Bundle branch and ultimately into the Purkinje fibers which first depolarize the endocardium of the ventricles and then the rest of ventricular musculature. SA Node --> Atria, AV node --> Bundle of His --> Right & Left Bundle Branches --> Purkinje fibers
What is the medial longitudinal fasciculus?
A bundle of fibers in the brainstem
Where is the Bundle of His in the heart?
In the Interventricular septum, between the right and left ventricles of the heart.
What is the part of the conduction system of the heart that wraps around in the outer walls of the ventricular is?
Purkinje Fibers
Which conducting fibers run down the ventricular septum?
AV Bundle
The correct sequence in the conduction system of the heart is?
SA node, Internodal pathways, AV node, Bundle of His, Bundle branches, Purkinje fibers.
Which structure spreads electric impulses from the interventricular septum to the Purkinje fibers in the ventricular wall?
AV Bundle
What is bundle of His in cardiology?
The Bundle of His (Hiss) is a bundle of electrical nodes which allow the ventricles to contract. The bundle is located in the ventricular septum which divides the two ventricles and separates into the Perkinje fibers at the apex of the heart. It is located in the myocardium.

What is The order of impulse conduction in the heart from beginning to end?
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.
Can you find nervous tissue in the heart?
The heart has several types of neural tissue. One is the sinoatrial node, the other is the atriole ventricular node. Then there is the the bundle of His, and the Purkengie fibers.
What are the bundle of nerve fibers?
VASICLES
What surrounds each bundle of nerve fibers?
A bundle of nerve fibers is surrounded by perineurium, a connective tissue that wraps around them.
What is the name of the structure in the heart which distributes the electrical impulses to the ventricles?
Bundle of Hisatrioventicular bundle (bundle of his), right and left bundle bramches and the purkinge conducition fibers
What is a bundle branch composed of?
Purkinje fibers.
