AV Bundle
the wall that divides heart cavity down middle is... septum...this is the TRUE answer... I hope thi helped you=}.
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.
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.
septum primum-type atrial septal defect due to endocardial cushion defects
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.
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.
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.

It is the SEPTUM
I think it is called the Septum.
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
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.
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.

Ventricular septal defect affects the ventricles common in babies with down syndrome while atrial septal defect is affecting the atrium.
Yes. Strenuous exercise can kill the muscle fibers. Such muscle fibers are replaced by fibrous tissue.
it breaks down the cellulose in the wood and plant fibers; it eats the wood and plant fibers
