Q

Where does the coronary sulcus lie?

A

Between the atria and ventricles

17
Q

What do the interventricular sulci do?

A

Separate the ventricles from one another

18
Q

What is a cardiac valve?

A

Endocardium with connective tissue core

19
Q

What is the role of the cardiac skeleton?

A

Anchors valve cusps
Prevents overdilation of valve openings
Blocks direct spread of electrical impulses

21
Q

What name is given to the ridges in the wall of the right atrium?

A

Pectinate muscles

22
Q

What is the fossa ovalis?

A

Depression in interatrial septum
Remnant of foramen ovale from embryology

A

Thin, upper part of the interventricular septum

26
Q

What is found in the internal wall of the ventricles?

A

Papillary muscles
Chordae tendinae

27
Q

What is found in the internal wall of the ventricles?

A

Trabeculae carneae
Papillary muscles
Chordae tendineae

28
Q

Name the atrioventricular valves.

A

Tricuspid valve
Bicuspid/mitral valve

29
Q

What is the structure of the atrioventricular valves?

A

Fibrous leaflets attached to fibrous ring which surrounds orifice

30
Q

What are the attachments of the chordeae tendineae?

A

Free margin and ventricular surface of leaflet
Papillary muscles

31
Q

When are the atrioventricular valves open and closed?

A

Open - diastole
Closed - systole

32
Q

How many cusps are in the semilunar valves?

A

3 pocket-shaped cusps

33
Q

What is valve stenosis?

A

Valve doesn’t open properly - narrow opening

34
Q

What is valve incompetence/regurgitation/insufficiency?

A

Valves does not close properly resulting in backflow
