What else can I help you with?
What size are the SA node?
AV ~1x3x5mm
Correct order of intrinsic cardiac conduction?
Its one of these, cant remember which one though: AV node, SA node AV bundle, Purkinje fibres. SA node, AV bundle, Purkinje fibres, AV node. SA node, AV node, AV bundle, Purkinje fibres. Purkinje fibres, SA node, AV node, AV bundle.
What if the av node malfunctions?
what are the causes of av node malfunction
The tertiary pacemaker is also known as the?
av node
The correct sequence in the conduction system of the heart is?
SA node, Internodal pathways, AV node, Bundle of His, Bundle branches, Purkinje fibers.
Is AV NODE known as pacemaker?
No, it is the SAN (sinoatrial node)
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 AV nodal delay?
AV node is responsible for the delayin transmission of impulse generated in the SA node.This delay of impulse transmissions is called AV nodal delay. It is about 0.09 sec.Causes of AV nodal delayi. Junctional fibres of the AV node are very small in size.ii. Prolonged refractory periodof AV node.
Do nerve impulses travel down the internodal pathways from the av node?
No, nerve impulses travel down the internodal pathways towards the AV node, not from it. The internodal pathways conduct the impulse from the SA node to the AV node, assisting in the synchronization of the heart's electrical activity.
What is the correct path for the transmission of an impulse in the instrinsic condition system of the heart?
sinoatrial (SA) node, atrioventricular (AV) node, atrioventricular (AV) bundle, right and left bundle branches, Perkinje fibers
What is the correct sequence of parts that function to carry cardiac impulses?
SA node, AV node, AV Bundle, Purkinje Fibers
How are the contractions of the 4 chambers in the heart coordinated?
SA node and AV node
