Definition
the first heart sound, referred to as S1.
it is associated with the closure of the AV valves, and the beginning of the ventricular systole |
|
|
Term
|
Definition
the second heart sound, also known as S2, occurs as the semilunar valves close.
it corresponds with the end of the systole |

|
|
Term
long strands of fiber like cells which support heart muscle in ventricular walls. (thicker in the left ventricle)
fibers that carry the cardiac impulse from the atrioventricular node to the ventricles of the heart and causes them to contract |

Term
| which two systems control heart activity ? |
|
Definition
- Autonomic Nervous System
- Nodal system
|
|
|
Term
intrinsic conduction system of the heart consisting of specialized noncontractile myocardial tissue.
it ensures that the heart muscle depolarizes in an orderly and sequential manner ( from atria to ventricles) and that the heart beats as a coordinated unit |
|
Definition
|
|
Term
| components of the nodal system |
|
Definition
Sinoatrial node (SA node)
Atrioventricular node (AV node)
AV bundle (Bundle of His)
Right and left bundle branches
Purkinje fibers
|
|
|
Term
|
Definition
provides the stimulus for contraction
sets the rate of depoarization for the heart as a whole, so it is referred to as the
pacemaker.
from this node, the impulse spreads thru the atria to the AV node this wave is followed by atrial contraction |
|
|
Term
| order that the impulses go thru the nodal system |
|
Definition
| SA node -> AV node (atrial contraction) ->AV bundle -> bundle branches -> Purkinje fibers -> (ventricular contraction ) |
