Surface anatomy of the heart Flashcards
name the 5 surfaces of the heart through it’s location in the mediastinum by it’s internal divisions
- anterior - right ventricle
- posterior - left atrium
- inferior (diaphragmatic) - L + R ventricle
- right pulmonary - right atrium
- left pulmonary - left atrium
Name the 4 borders of the heart
- right border - right atrium
- left border - left ventricle + some left atrium
- inferior border - L + R ventricle
- superior border - L + E atrium, great vessels
what are sulci of the heart?
grooves on the outside of the heart created from the internal division of the 4 chambers
What is the coronary sulcus?
atrioventricular groove - runs transversely across the heart
wall dividing atria from ventricles
coronary sulcus contains right coronary artery
anterior + posterior interventricular sulci
walls separating ventricles - where the most anterior to inferior coronary artery runs
what are pericardial sinuses?
‘passageways’ in which pericardium folds around the great vessels
oblique pericardial sinus
posterior of the heart
where you put your whole hand under
‘cul de sac’ - blind ending passageway
transverse pericardial sinus, use?
superior of the heart
used for coronary artery bypass grafting
put your fingers through
transverse pericardial sinus location?
posterior: ascending aorta + pulmonary trunk
anterior to: superior vena cava
Superior to: left atrium
what does the transverse pericardial sinus separate?
arterial from venous vessels of the heart
arterial: pulmonary trunk + ascending aorta
venous: superior vena cava + pulmonary veins
transverse pericardial sinus clinical function?
ligate arteries of heart during coronary artery bypass grafting
describe the position of where the heart lies
hollow muscular pump in the middl mediastinum
