What else can I help you with?
What structure completely separates the atria from the ventricles?
septum
Structure that carries the heart electrical impulse into the ventricle?
The structure that carries the heart's electrical impulse into the ventricles is called the bundle of His. It is a collection of specialized muscle fibers located in the walls of the heart's chambers that conducts the electrical signal from the atrioventricular node to the ventricles, initiating their contraction.
What structure of the conduction system helps to cause the constriction of the ventricles and extend from the atrioventricular node?
The bundle of His, also known as the atrioventricular bundle, is the structure of the conduction system that helps to coordinate the contraction of the ventricles. It extends from the atrioventricular node and transmits electrical impulses to the Purkinje fibers, which then cause the ventricles to contract simultaneously.
What structure communicates the lateral ventricles with foramen of Monro?
The foramen of Monro connect the lateral ventricles with the third ventricle.
What cardiac structure is poorly innervated by the parasympathetic nervous system?
Ventricles
What is the name of the structure in the heart which distributes the electrical impulses to the ventricles?
Bundle of Hisatrioventicular bundle (bundle of his), right and left bundle bramches and the purkinge conducition fibers
In the human heart the muscular structure of the ventricles enables them to?
Pump blood directly to the atria.
What structure connects the cusps of the AV valves to the ventricles?
papillary muscles
What external structure of the heart marks the position of the junction between the atria and the ventricles?
coronary sulcus
Which structure of the heart provides the stimulation that causes the ventricles to contract?
purkinje fibers
What is the structure that prevents blood from flowing back into the atria when the ventricles contract?
man someone help me
What structure conducts the contraction impulse from the atria to the ventricles?
the purkinje fibers um no!!! wrong answer!!
