Heart Flashcards
What is the smooth part of the right atrium called?
Sinus venarum cavarum
What are the muscles in the rough parts of the atria called?
Pectinate muscles
The orifice of which vein can be found medially to the inferior vena cava?
Coronary sinus
What is the valve between the right atrium and ventricle called?
Right atrioventricular valve, tricuspid valve
What is the name of the tendinous chords attached to the valves?
Chorda tendinae
What is the muscular projections into the ventricles called?
Papillary muscle
What are the muscular structures in the walls of the ventricles called?
Trabeculae carneae
Where can the septomarginal trabeculae be found?
Right ventricle
What is the structure that separates the smooth and rough part of the right atrium called?
Crista terminalis
What is the name of the valve of the inferior vena cava?
Eustachian valve
What is the valve of the coronary sinus called?
Thebesian valve
What structure can be seen from the outside of the heart and is continuous with the rough atrium?
The auricle
Does superior vena cava have a valve?
No
Where does the blood from the coronary sinus come?
From the heart itself
Is through the coronary sinus the only place the heart empty venous blood into the right atrium?
No, at various sites the tinniest cardiac veins empty via minute openings into the right atrium.
The crista terminalis will create a slight depression visible on the outside of the heart. What is it called?
The sulcus terminalis cordis
The interior of the right ventricle is divided by two muscular ridges. Which?
The supraventricular crest and the septomarginal trabeculae
Which ventricle has the thickest muscle wall?
The left ventricle
How many cusps, or leaflets, does the right atrioventricular valve have?
Three - tricuspid
What is the smooth walled part of the right outflow tract called?
Conus arteriosus (infundibulum)
How many cusps does the pulmonary valve have?
Three semilunar cusps
Which of the pulmonary veins have valves?
Non of them
What is the calve between the left atrium and ventricle called?
Left atrioventricular valve, bicuspid valve, mitral valve
How many leaflets does the mitral valve have?
Two
