The string-like structures that anchor the valve flaps of the AV valves are called?
The string-like structures that anchor the valve flaps of the AV valve are called the chordae tendinae, which attach to the papillary muscles of the ventricles. Interestingly enough, the bundle branches extend down and into the areas where the papillary muscles are located, and the resulting contraction of the ventricles ensures that the papillary muscles pull the valves tight, ensuring that they are closed thoroughly to prevent backflow in the heart.

What are the ropelike structures at the base of the tricuspid and aortic valves?
The ropelike structures at the base of the tricuspid and aortic valves are called chordae tendineae. They are cord-like tendons that connect the valve cusps to the papillary muscles in the heart. These structures help to prevent the valves from prolapsing or regurgitating when the heart contracts.
What structures anchor the atrioventricular valves to the papillary muscles of the ventricle walls?
The structures that anchor the atrioventricular valves to the papillary muscles of the ventricle walls are the chordae tendineae. These are tough, string-like tendons that connect the valve leaflets to the papillary muscles, preventing the valves from prolapsing into the atria during ventricular contraction.
What are the the tiny white cords that anchor the cusps or flaps of endocardium to the walls of the ventricles called?
The tiny white cords that anchor the cusps or flaps of endocardium to the walls of the ventricles are called chordae tendineae. These cord-like structures help prevent the cusps of the heart valves from prolapsing into the atria when the heart contracts.
What structures in the heart prevent the back flow of blood?
The heart has two types of valves that keep the blood flowing in the correct direction. The valves between the atria and ventricles are called atrioventricular valves (also called cuspid valves), while those at the bases of the large vessels leaving the ventricles are called semilunar valves.
What structure prevents the valves from turning inside out?
The chordae tendineae, also known as the heart strings, are fibrous tendons that anchor the heart valves in place and prevent them from turning inside out during the cardiac cycle. These tendons are connected to the papillary muscles in the heart to ensure proper valve function.
What are the string-like structures that attach to the atrioventricular valves of the heart?
Chordae tendinae are the string-like structures that attach to the AV valves of the heart.
What structures of the heart can be assessed by heart sounds?
valves
What structures of the heart keep blood flowing in one direction?
Valves
What is considered upper heart valves?
The upper heart valves are called atriums, and the lower heart valves are called ventricles.
Is true the chordae tendineae anchor the semilunar valves to the walls of the ventricles?
No. in my opinion, Chordae tendineae is attached to Tricuspid valve and bicuspid valve. Both valves do not have semilunar valves. Pulmonary valve and Aortic valve has semilunar valve.
What are the fibrous structures in the heart that prevent prolapse of the cuspid valves?
Chordae tendineae - attached to the valves between both atria and ventricles... these structures are attached to papillary muscles in the bottom of the ventricles. these contract when the valves contract, this keeps the blood from going back up into the atria.
What are the valves that prevent blood from flowing back into the atria called?
The valves that prevent blood from flowing back into the atria are called atrioventricular valves.
