What are the three pericardium layers of the heart
Fibrous
Serous
-Parietal
-Visceral
What is pericarditis?
Inflammation of the serous pericardium producing audible rubbing (like silk)
Where should a person perform a pericardiocentesis (3 places)?
5th or 6th intercostal space
infrasternal angle
Why is the transverse sinus an important landmark?
It is the area that separates the outflow and inflow great vessels?
Phrenic nerves refer to what dermatome when there is pericardium pain?
C3-C5 dermatomes
How are septa on the heart identified from the outside?
Sulci (sulcus) = grooves
At what intercostal region is the apex of the heart found?
5th intercostal region
Where in the heart can you find deoxygenated blood?
Right from superior and inferior vena cava
At what vertebral level do you find the posterior base of the heart?
T6-T9
Right Atrium
Right Auricle
Sinus Venarum
Pectinate muscle
Cristae terminalis
Interatrial septum
Fossa ovalis
opening of coronary sinus
Atrioventricular valve (tricuspid)
Where can you find the superior vena cava?
3rd costal cartilage
Where can you find the inferior vena cava?
5th costal cartilage
Right Ventricle
Conus arteriosus
trabeculae carnae
chordae tendinae
papillary muscles
interventricular septum
septomarginal trabecula
Pulmonary valve (semilunar valve)
Left Atrium
Left Auricle
Valve of fossa ovalis
Semilunar depression
Mitral valve
Left ventricle
Chordae tendinae
Papillary muscle
Trabeculae carnae
Atrial valve (semilunar)
When do coronary arteries fill, diastole or systole?
Diastole
What happens at diastole and systole?
Diastole
: Semilunar valves close, Mitral and tricuspid valves open
Systole
: Semilunar valves open, mitral and tricuspid valves close
Systole = "S"queeze
Diastole = "D"ump
Heart vasculature: arterial supply
Right coronary artery
Sinoatrial node branch
Right marginal branch
posterior interventicular branch
atrioventricular nodal branch
Left coronary artery
left anterior descending artery
circumflex branch
left marginal branch
Heart vasculature: Venous drainage
coronary sinus
great cardiac vein
middle cardiac vein
small cardian vein
Heart lymphatic drainage
Left ventricle = right lymphatic duct
Right ventricle = thoracic duct
Heart conduction pathway
Sinoatrial node
Atrioventricular node
AV bundle of His
R & L AV bundles
Interventricular septum moderator band (RV)
Purkinje fibers
***contraction initiates at apex
