where pulmonary trunk arises

20
Q

Trabeculae Carneae

A

rough muscle on wall of ventricles

21
Q

Interventricular septum

A

wall between left and right ventricle

membranous and muscular portion

22
Q

Interatrial Septum

A

Wall of atrium

smooth because it was a blood vessel at one time

Q

Interventricular Septum- Membranous Portion

A

Thinnest part of ventricular wall

Where VSD’s occur

24
Q

Interventricular Septum- Muscular Portion

A

Thickest part of ventricular wall

25
Q

Papillary Muscles

A

come from ventricle wall and connect to chordae tendinaea to open and close valves

26
Q

When are valves of the heart open?

27

33
Q

Left Fibrous Trigone

A

attaches mitral valve and aortic semi-lunar vlave

34
Q

Right Fibrous Trigone

A

attaches atrioventricular valves to aortic semi-lunar valves

35
Q

Coronary Sinus

A

Main drain vein for the heart vessels into the right atrium

36
Q

Great cardiac vein

A

In front/ anterior

drains into coronary sinus

37
Q

Middle cardiac vein

A

in the middle back of the heart

drains into coronary sinus

38
Q

A

Off the right side of the heart

drains into coronary sinus

39
Q

Anterior cardiac vein

A

sits right by right atrium

Drains directly into right atrium

40
Q

Does the heart have somatic feeling?

A

No, but it does feel chemistry (i.e. stretch)

41
Q

What nerve innervates the heart?

A

cardiac plexus
sympathetic trunk with vagus
cervical splanchinics

42
Q

What level are the cervical splanchnics located at?

43
Q

How are the valves located in the heart?
