Are autorhythmic cells located only in the interventricular septume?
Not exclusively:Cardiac Muscle cells are either contractile cells or autorhythmic cells. The majority are contractile.Examples of autorhythmic cells:Sinoatrial (SA), or Sinus, NodeAtrioventricular (AV) NodeAtrioventricular (AV) Bundle (occasionally referred to as the bundle of His)Right and Left Bundle BranchesPurkinje Fibers
How do the waves of depolarization generated by the autorhythmic cells spread to the muscle cells?
Gap Junctions in the cell spread the action potential to nearby cells.
What cells stimulate both atria to contract?
Nodal or pacemaker cells.
What does auto rhythmic mean?
Autorhythmic cells (pacemakers) refers to the cardiac muscle cells responsible for synchronizing the contractile cells to coordinate a heart contraction.
What does auto-rhythmic mean?
Autorhythmic cells (pacemakers) refers to the cardiac muscle cells responsible for synchronizing the contractile cells to coordinate a heart contraction.
Which type of muscle tissue is autorhythmic?
cardiac muscle
Is it true that av nodal cells are poorly interconnected to contractile cells but they have bigger diameters?
They are poorly interconnected, but they do not have larger diameters.
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.
What is a nodal point?
Nodal point in logistics
When do we call a city a nodal city?
nodal city
How are the heart impulses detected?
The Pacemaker cells of the Sinoatrial Node spontaneously initiates the impulse. Without stimulation from nerve fibers or any other outside agents, the nodal cells initiate impulses that spread into the surrounding myocardium and stimulate cardiac muscle fibers to contract.
When did John Howard Nodal die?
John Howard Nodal died in 1909.
