Anatomy Lab 7 Heart dissection

apex

what’s the pointed/inferior region of the heart?

base

what is the superior region of the heart?

what is the region where blood vessels exit?

right atrium

auricle ; right atrium

the flaps on the real heart

left atrium

auricle ; left atrium

the flaps on the real heart

right ventricle

Orange portion above it

left ventricle

Orange portion above it

anterior interventricular sulcus

(white groove that separates ventricles on anterior side)

posterior interventricular sulcus

(white groove that separates ventricles on posterior side)

Right Coronary Artery (RCA)

Abbreviation = RCA

marginal branch ; RCA

posterior interventricular branch ; RCA

line through

left coronary artery (LCA)

anterior interventricular branch ; LCA

line through

circumflex branch ; LCA

runs with the great cardiac vein

great cardiac vein

runs with the circumflex branch ; LCA

superior vena cava

inserts through the right atrium

Inferior vena cava

inserts through the right atrium

aortic arch

ascending aorta

is slightly posterior and is to the right of the pulmonary trunk

pulmonary trunk

is slightly anterior and is to the left of the ascending aorta

left pulmonary artery

blue

right pulmonary artery

blue

pectinate muscle

found on the auricle of the right and left atrium wall

tricuspid valve

AKA: right atrioventricular valve, (Found on top of the chordae tendineae)

chordae tendineae

the little strings below the tricuspid and bicuspid valve

interatrial septum

what the walls between the atriums?

fossa ovalis

depression on the right atrium

coronary sinus

(can only see on the real model)

pulmonary semilunar valve

valve inside the pulmonary trunk (no strings attached)

interventricular septum

papillary muscle

muscle that attaches to the chordae tendineae

moderator band

found only on the right ventricle (you can find this only on the real heart model)

trabeculae carneae

surface on the inside ventricle walls (Freddy Krueger skin)

left pulmonary vein

red

right pulmonary vein

red

aortic semilunar valve

valve inside the ascending aorta (no strings attached)

bicuspid valve

AKA: mitral valve or left atrioventricular valve
