What divides heart into to sides?
the wall that divides heart cavity down middle is... septum...this is the TRUE answer... I hope thi helped you=}.
What is the conductive tissue in the wall between the ventricles?
In the interventricular septum lies the hindle of His (pronounced hiss) and the bundle branches. These structures carry the impulses from the AV node down to the purkinje fibres.
What part of the heart's conduction system acts as the primary pacemaker?
The atrioventricular (AV) node which is located in the right atrium. From there is travels down the septum, also called the atrioventricular bundle, and then spreads to all parts of the ventricles via the Purkinje fibers.
Which is the most common congenital heart defect in people with Down syndrome?
septum primum-type atrial septal defect due to endocardial cushion defects
Do you have nerves in your heart?
Yes, but not somatic nerves. Instead the heart is enervated by the autonomic nervous system (used mainly to speed up and/or slow down the heart rate). There is also an internal set of nerves (referred to as Perkingi fibers) that are used to synchronize the beats of the heart.
Which fibers spread the electrical signal throughout the ventricular walls?
Purkinje cells are specialized cardiac cells, whose purpose it is to spread the electrical signal from the atrioventricular (AV) node down through the right and left ventricles.
Are moderator band and Purkinje fibers branches of Atrioventricular bundles?
Yes, the Purkinje fibers branch from the atrioventricular node down through the interventricular septum and traven through the walls of the heart. A branch leaves the wall and travels through/with the moderator band.

What is the wall that divides heart cavity down the middle?
It is the SEPTUM
What divides the heart down the middle?
I think it is called the Septum.
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 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.
What is the conductive tissue in the wall between the ventricles?
In the interventricular septum lies the hindle of His (pronounced hiss) and the bundle branches. These structures carry the impulses from the AV node down to the purkinje fibres.
What separates the two nasal cavities?
What is the bony separation between the nasal passage called
How is a ventricular septal defect different from an atrial septal defect?
Ventricular septal defect affects the ventricles common in babies with down syndrome while atrial septal defect is affecting the atrium.
What impulse is carried down the septum?
The impulse carried down the septum is the electrical signal generated by the heart's conduction system, specifically from the atrioventricular (AV) node through the bundle of His. This signal travels along the interventricular septum, branching into the right and left bundle branches, which then distribute the impulse to the ventricles. This coordinated transmission ensures that the ventricles contract in a synchronized manner, allowing for effective blood pumping.
Describe the pathway of nerve impulses through the heart?
The normal, or natural, pacemaker of the heart is the sinoartial node, it passes the action potential to the ventricular node, which slows it down long enough for the ventricles to fill up with blood. Then the second contraction is triggered by the action potential traveling down the Bundle of His, or atrioventricular bundle, and then spread out the signal to the Purkinje fibers which transmit the action potentiall to all parts of the ventricles.
